1886 - A hurricane from the Gulf of Mexico crossed Florida causing great damage from Cedar Keys to Jacksonville. (David Ludlum)

1886: The 1886 Atlanta Hurricane season was a very active year with ten hurricanes, seven of which struck the United States. During the evening hours of July 18th, a category 1 storm made landfall near Homosassa Springs, Florida. Damage was slight as the area was thinly inhabited. The hurricane weakened to tropical storm status south of Gainsville and emerged on the eastern side of Florida, south of Jacksonville during the morning hours of the 19th. This was the fourth hurricane to make landfall in the United States. 

1960 - Cow Creek and Greenland Ranch in Death Valley, CA, reported morning lows of 102 degrees. The afternoon high at Greenland Ranch was 124 degrees, and the high at Cow Creek that afternoon was 126 degrees. The coolest low for the entire month for both locations was 82 degrees. (The Weather Channel)

1974 - A severe thunderstorm with winds to 80 mph and up to two inches of rain washed out four to five foot deep sections of roadway in Lake Havasu City, AZ. Three persons in a station wagon died as it was carried 3000 feet down a wash by a ten foot wall of water. (The Weather Channel)

1977 - Thunderstorms produced torrential rains over parts of southwestern Pennsylvania. Some places receive more than twelve inches in a seven hour period. The heavy rains cause flash flooding along streams resulting in widespread severe damage. The cloudburst floods Johnstown with up to ten feet of water resulting in 76 deaths, countless injuries, and 424 million dollars damage. (David Ludlum) (The Weather Channel)

1987 - Fifteen cities in the western and the southeastern U.S. reported record low temperatures for the date, including Winnemucca, NV, with a reading of 33 degrees. Flagstaff AZ reported a record low of 34 degrees. Afternoon and evening thunderstorms produced severe weather in New York State and New Jersey. High winds and hail two inches in diameter injured two persons and caused considerable damage to crops in the Pine Island area of central New York State. (The National Weather Summary) (Storm Data)

1988 - Thunderstorms in Nebraska produced more than five inches of rain at Red Cloud, including two inches in fifteen minutes. Torrid temperatures continued over California, with record highs of 115 degrees at Red Bluff and 116 degrees at Redding. (The National Weather Summary) (Storm Data)

1989 - Early morning thunderstorms in the Lower Mississippi Valley produced 5.50 inches of rain south of Alexander, AR, in just ninety minutes, and flash flooding which resulted claimed the life of one woman. Thunderstorms in Indiana produced 4.95 inches of rain in twelve hours east of Muncie. Eight cities in the southwestern U.S. reported record high temperatures for the date, including Las Vegas, NV, with a reading of 115 degrees, and Phoenix, AZ, with a high of 116 degrees. The low that night at Phoenix of 93 degrees was the warmest of record for that location. (The National Weather Summary) (Storm Data)

2005 - A severe heat wave gripped the region during early to mid-July. Las Vegas, NV tied their all-time record high temperature of 117 degrees, equalling the old record set on July 24, 1942.

2006 - The first of two severe thunderstorms hits the St. Louis area, causing the largest power outage in the city's history with over 570,000 people losing electricity.

2006: A derecho impacted a sellout crowd of almost 44,000 St. Louis Cardinals fans, packed into the new Busch Stadium. Winds of about 80 mph whirled around the St. Louis area, sending the fans running for shelter. The winds knocked out power and broke windows out of the press box. Nearly two minutes after the winds began at 100 mph, they stopped, and it started to rain. In all, about 30 people were injured at the stadium.

With a break in the 95° to 100° heat in the forecast, Hightstown in Mercer County only needs 2 more 95° days for the new all time record for a year. The previous record was set in 2002.  The sea breeze influence has been so strong that places like Newark on the bay have been lagging behind. Harrison a little further from the bay made it to 101° during this most recent heatwave while Newark maxed out at 99°.

72 / 64 - Mainly cloudy.    Dewpoints slowly creeping up. Hung up front to the south and showers possible in southern areas.  Clouds keep a lid on temps mid - upper 80 (where there are breaks).  We'll see how much we can clear tomorrow (which could be the sunniest/driest day of the next 6.  Upper 90s.  Atlantic ridge but up against the SE coast with front nearby.  Overall warm / stormy this week - chance of storms/showers Mon - Fri,  clearing possible which heats it quickly.  Mainly mid - upper 80s stray 90 on the clearer days in the warm spots.   Sat 7/27 and beyond looks a bit drier and should get us back near / low 90s Western ridge expanding N and E. 

 

7/20 - 7/26 : Near normal, storms, showers each day, humid
7/27 - beyond :  Overall warm/ humid above normal - hotter towards the 29.

Could be some ridiculously high rainfall totals next few weeks where the front stalls out and best training occurs. The ensemble means are some of the wettest we have seen for late July in the East. So a slightly stronger WAR could push the heaviest axis a little closer to region in later runs. Plus the globals tend to underestimate convective rains while the shorter term CAMS like the HREF do better. This is really impressive considering it’s coming at a time when the tropical Atlantic is quiet.

No question about that. After several dry days, we'll be wanting some rain next week. Right now it appears that we have a good chance of seeing some showers/storms Monday night. Wednesday has been advertised as a stormy day, but I see the models backed off on that. Euro is dry for Wednesday now. Of course we have a ways to go to figure out the timing of the potential rounds of rain for next week.

July is the only month with >100F highs at NYC that are not daily records. June peaks at 98F and August 100F for non records.

This is the full list of 100F days at NYC, showing which ones were not daily records ... 99F in may 1962 did not quite start the listing, nor did several 99F in June 1925 nor one in June 1956. None of dates mentioned saw a second place value above 96F but 99F tied 1943,52 for 06-25 had a 97 (1923) in third place

Generally fair and somewhat warmer than normal readings will prevail into next week. Some showers or thundershowers could become likely toward the middle of next week.

The latest summer guidance continues to suggest a warmer to much warmer than normal summer lies ahead. Some of the extended range guidance suggests that August could be warmer to much warmer than normal.

The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was 0.3°C for the week centered around July 10. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.47°C and the ENSO Region 3.4 anomaly has averaged +0.23°C. Neutral ENSO conditions will likely evolve into a La Niña event during the late summer or early fall.

The SOI was -22.47 today.

The preliminary Arctic Oscillation (AO) was -0.013 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 94% probability that New York City will have a warmer than normal July (1991-2020 normal). July will likely finish with a mean temperature near 80.2° (2.7° above normal). That would tie 2024 with 2011 as the 6th hottest July on record.

Historical:

 

1915: A record high temperature of 115 degrees occurred in Yosemite Valley at the National Park Headquarters, California (around 4,000 feet elevation). This reading was the warmest day in a streak of 7 consecutive days of 110 degrees or higher at Yosemite Valley from the 19th through the 25th.

 

1930 - The temperature at Washington D.C. soared to an all-time record of 106 degrees. The next day Millsboro reached 110 degrees to set a record for the state of Delaware. July 1930 was one of the hottest and driest summers in the U.S., particularly in the Missouri Valley where severe drought conditions developed. Toward the end of the month state records were set for Kentucky with 114 degrees, and Mississippi with 115 degrees. (David Ludlum)

1934 - The temperature at Keokuk, IA, soared to 118 degrees to establish a state record. (The Weather Channel)

1953 - Twenty-two inches of hail reportedly fell northeast of Dickinson, ND. (The Weather Channel)

 

1977: A flash flood hits Johnstown, Pennsylvania, on this day in 1977, killing 84 people and causing millions of dollars in damages. This flood came 88 years after the infamous Great Flood of 1889 that killed more than 2,000 people in Johnstown.

1986 - The temperature at Charleston, SC, hit 104 degrees for the second day in a row to tie their all-time record high. (The Weather Channel)

1987 - Thunderstorms produced severe weather across Minnesota, Wisconsin and Michigan. Thunderstorms produced wind gusts to 87 mph at Mosinee, WI, and strong thunderstorm winds capsized twenty-six boats on Grand Traverse Bay drowning two women. Thunderstorms produced nine inches of rain at Shakopee, MN, with 7.83 inches reported in six hours at Chaska, MN. Thunderstorms in north central Nebraska produced hail as large as golf balls in southwestern Cherry County, which accumulated to a depth of 12 inches. (The National Weather Summary) (Storm Data)

1988 - The temperature at Redding, CA, soared to an all-time record high of 118 degrees. Showers and thunderstorms produced much needed rains from New England to southern Texas. Salem, IN, was deluged with 7.2 inches of rain resulting in flash flooding. (The National Weather Summary)

1989 - Showers and thunderstorms in the Middle Atlantic Coast Region soaked Wilmington, DE, with 2.28 inches of rain, pushing their total for the period May through July past the previous record of 22.43 inches. Heavy rain over that three month period virtually wiped out a 16.82 inch deficit which had been building since drought conditions began in 1985. Thunderstorms in central Indiana deluged Lebanon with 6.50 inches of rain in twelve hours, and thunderstorms over Florida produced wind gusts to 84 mph at Flagler Beach. (The National Weather Summary) (Storm Data)

2005: Hurricane Emily made landfall in northern Mexico. When the central pressure fell to 29.43 inches of mercury, and its sustained winds reached 160 mph on the 16th, Emily became the strongest hurricane ever to form before August, breaking a record set by Hurricane Dennis just six days before. It was also the earliest Category 5 hurricane ever recorded in the Atlantic basin, beating Hurricane Allen's old record by nearly three weeks.

Yeah, parts of the Northeast can make a run on 100” of precipitation since last July as we approach the peak of the hurricane in September.

77 / 67 (dewpoints rising)..  Cleared from yesterday, what will likely be the driest, and warmest day of the next 5.   Upper 80s to low 90s today in the warm spots.  Scattered showers possible later.  Week looks to include showers/storms chances each day,very humid and remain mostly cloudy, keeping temps in the 80s/70s most days.  Drier but still not completely by the weekend as the ridge builds north of us.  Warmer - hotter by 29th.  Western heat building in north and east, onshore flow keeps the hottest inland as it looks now, but an overall hotter look from the 29th and beyond.

Has the ridge north look / onshore component with stronger heat north and inland initially in day 7 - 10. Could be continued somewhat stagnant flow Humid/Hot and ran chances.  Atlantic ridge continues to stay anchored and expand in periods.  Ridge pushing east of HI has weaker trough into the or off of the WC.
