I am NOT seeing any prolonged or sustained warmth in this pattern. We break out of the current cold pool in the upper atmosphere and enjoy moderation to near or perhaps slightly above normal temperatures for a day or two next week (thinking mainly upper 70s perhaps one day lower 80s) but I think we're going to re-load the extremely wet pattern of the last 6 days by around the 11th. For sustained warmth or even heat I think we'll have to wait until the last ten days of the month or in June.

I am not seeing any evidence of another cooldown next week.

You need to hang out next to the Newark ASOS, somehow they managed 60 degrees yesterday.   You know you have a problem when it's 2-3 degrees too warm in what should be uniform conditions.

They had more breaks of sun than some of the surrounding sites. You can see them running close on the high for the month so far. Each day has been slightly different with cloud over from station to station with the cold pool.

Weather looks good after tomorrow. 

Weekend looks great. I don't see any major heat for now. Temperatures will probably stay close to seasonable levels averaged out. 

3rd week of May could be cooler though. 

[donsutherland1]

Temperatures rose mainly into the middle 50s. Tomorrow will be somewhat warmer, as temperatures begin to moderate.

Readings will reach normal levels by Sunday and then go above normal early next week as the ongoing blocking regime fades and warmer air comes eastward. The duration and magnitude of this warm period could determine the overall monthly temperature anomaly.

Typically, a very warm April is followed by a somewhat cooler than normal May in the Middle Atlantic region. Whether that will be the case this year remains to be seen.

The ENSO Region 1+2 anomaly was +2.4°C and the Region 3.4 anomaly was +0.4°C for the week centered around April 26. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.37°C and the ENSO Region 3.4 anomaly has averaged +0.13°C. Neutral ENSO conditions will likely prevail through at least mid-spring. El Niño conditions will very likely develop during the summer.

The SOI was -9.48 today.

The preliminary Arctic Oscillation (AO) was -0.608 today.

On May 2 the MJO was in Phase 4 at an amplitude of 2.497 (RMM). The May 1-adjusted amplitude was 2.369 (RMM).

The timing is uncertain but you're always promoting warmth. That's awfully nice of you. But the models are mixed as to whether there'll be much if any. It's predominantly slightly below normal temperatures to slightly above normal temperatures and there's no sustained or big-time warm-ups or heat on these maps. Whenever there is the highly energized storm track to cut it off.  Below is an example:

But at least if we stay around average to slightly above that means mid-60's to lower 70's, which is great.  The last few days that have been stuck in the low 50's are well below normal, and after tomorrow should hopefully be done for good.  I agree no "big" heat signal coming up, but I think most of us are just looking for some nice sunny spring days anyway.

Historical:

 

1917 - The same storm which a day earlier produced eight inches of snow in the Texas panhandle, produced a foot of snow at Denver CO, their heaviest snow of record for the month of May. (David Ludlum)

1930 - The temperature at College Park, VA, soared from 43 degrees to 93 degrees to begin an exceptional heat wave. (Sandra and TI Richard Sanders - 1987)

 

1933: An estimated F4 tornado cut a 35-mile path from near Brent into Shelby County, Alabama. The town of Helena, AL was especially hard hit, as 14 people died. The tornado roared through Helena at 2:30 am.

1987 - Unseasonably hot weather prevailed in the western U.S. A dozen cities in California reported record high temperatures for the date. Afternoon highs of 93 degrees at San Francisco, 98 degrees at San Jose, 100 degrees at Sacramento, and 101 degrees at Redding, were the warmest of record for so early in the season. The high of 94 degrees at Medford OR was also the warmest of record for so early in the season. (The National Weather Summary)

1987 - Parts of the western U.S. were in the midst of a blistering May heat wave. The reading of 100 degrees in Downtown Sacramento CA was their earliest of record. Sacramento CA established daily record highs on nine of eleven days between the 4th and the 14th. (The Weather Channel)

1988 - A stubborn low pressure system continued to drench the eastern U.S. with rain. Thunderstorms again produced large hail in North Carolina. (The National Weather Summary)

1989 - Thunderstorms swept across Georgia and the Carolinas during the late afternoon and evening hours spawning seventeen tornadoes. A tornado at Toccoa GA injured 15 persons, and a tornado at Chesnee SC killed two persons and injured 35 others. Five tornadoes in North Carolina accounted for five deaths, 88 injuries, and sixty million dollars damage. Thunderstorms also produced baseball size hail at Lake Murray SC, and wind gusts to 78 mph at Brooklyn MD. (The National Weather Summary) (Storm Data)

1990 - A strong Pacific cold front moving rapidly inland caused weather conditions at the east end of the Strait of Juan de Fuca in Washington State to quickly change from sunny and calm to westerly winds of 60 mph and ten-foot waves. Three recreational fishing boats capsized in heavy seas off Port Angeles resulting in five deaths. In California, temperatures soared above 90 degrees across much of the state. The high of 101 degrees in downtown Los Angeles was eight degrees hotter than their previous record for the date. (The National Weather Summary) (Storm Data)

 

1995: A supercell thunderstorms brought torrential rains and large hail up to four inches in diameter to Fort Worth, Texas. This storm also struck a local outdoor festival known as the Fort Worth Mayfest. At the time the storm was the costliest hailstorm in the history of the US, causing more than $2 billion in damage.

Down to 40 and now to 59.  Larger breaks as we begin the slow clearing out of this mess. Should be break the sub 60 stretch for most today and back to 70s this weekend.  Perhaps a nice weekend for once with sun and dry / no rain.  Some of the warmer spots can get to or touch near 80 on Mon (5/8)

guidance seems to be a bit warmer than prior runs after mid may. More of a back and forth, no sustained or strong departures either way.  Still looks like numerous precip chances through the period.

EPS has a stout western north American ridge and troughing closer to us which should trend stronger

A warming trend is now getting underway. A glorious sun-filled weekend with readings in the upper 60s and lower 70s lies ahead.

Readings will reach normal levels by Sunday and then go above normal early next week as the ongoing blocking regime fades and warmer air comes eastward. The duration and magnitude of this warm period could determine the overall monthly temperature anomaly.

Typically, a very warm April is followed by a somewhat cooler than normal May in the Middle Atlantic region. Whether that will be the case this year remains to be seen.

On May 3 the MJO was in Phase 4 at an amplitude of 2.471 (RMM). The May 2-adjusted amplitude was 2.501 (RMM).

Beautiful moon rise this evening. Finally a full nice dry weekend on tap. I know @nycwinterwill still be wearing his Canadian goose in the morning haha 

Enjoy the weekend fellas!

The next 8 days are averaging     64degs.(55/74) or +2.

Reached 61 here yesterday.

Today:    69-74, wind nw. to w., m.sunny, 55 tomorrow AM.

51*(86%RH) at 7am.     53* at 8am.    56* at 9am.      59* at 10am.       60* at 10:30am.       59* at 11am.      61* at Noon.      65* at 2pm.       70* at 3:30pm.       71* at 4pm.       67* at 4:30pm. ---puffy cumulus and some sea breeze kept T down.

Mid-month change?    EURO seems very warm at mid-month.

[nycwinter]

even with a cool airmass this morning under the blistering may sun it felt much warmer i might not be able to wear my hoodie much longer..

[SACRUS]

 

Down to 41 last night and now up to 65.  Bright sunshine on a weekend - First 70s since April 23 for most.   Tomorrow may be a bit more cloudy but more 70s.  Mon (5/8)  depending on sunshine could touch near or get to 80 in the warmer spots.   A bit cooler Tue (5/9) and Wed (5/10) back to the 60s before warming up the end of the week and into Mothers day where perhaps more widespread 80s are possible.  No large rain makers on the table this week but wouldnt rule out showers overnight Sunday and again mid week.  Beyond there a bit back and forth no real sustained or strong departures either way - so near normal. In the way beyond perhaps more ridging coming to end the month.  PAst very cool mays did turn hot at a point.

Gorgeous day here in New England this AM. Currently 62F, I  couldn't have picked a better day to put the boat in the lake.

Historical: 

 

1876: A tornado, estimated at F3 intensity, tracked four miles across Chicago, Illinois. The damaged buildings included a candy factory, a hospital, a freight depot, and a church. The tornado moved out over Lake Michigan and was observed to have multiple vortices by a reporter. Further south in Illinois, a tornado blew a moving passenger train off the tracks near Neoga, injuring all 19 people aboard. 

1933 - Charleston, SC, was deluged with 10.57 inches of rain, an all- time 24 hour record for that location. (The Weather Channel)

 

1975 - A massive tornado hit Omaha, NE, killing three persons, injuring 133 others, and causing 150 million dollars damage. The tornado struck during the late afternoon moving northeastward through the industrial and residential areas of west central Omaha, and lifting over the northern section of the city. The twister, which cut a swath ten miles long and as much as a quarter of a mile wide, was the mostly costly in U.S. history up til that time. (David Ludlum)

1987 - Eighteen cities in California and Oregon reported record high temperatures for the date. Highs of 91 degrees at Portland OR, 101 degrees at Medford OR, and 104 degrees at Sacramento CA, were the warmest of record for so early in the season. (The National Weather Summary)

1988 - A major storm brought high winds to the western half of the country. A wind gust of 74 mph at Pueblo CO broke their May record established just four days earlier, and winds in the Arapahoe Ski Basin area of Colorado reached 85 mph. In North Dakota, the high winds reduced visibilities to near zero in blowing dust closing many roads. (The National Weather Summary) (Storm Data)

1989 - Sixteen cities in the north central U.S. reported record low temperatures for the date. Morning lows of 17 at Bismarck ND and 26 at Minneapolis MN were the coldest of record for so late in the season. A reading of 43 degrees at the start of the Kentucky Derby was the coldest in 115 years of records. Light snow was reported in the Upper Midwest, with an inch reported at Chicago IL. (The National Weather Summary)

1990 - Snow and high winds prevailed behind a Pacific cold front crossing the northwestern U.S. Wind gusts above 50 mph were reported in southeastern Idaho, and heavy snow blanketed the Cascade Mountains of Washington State, with twelve inches reported at Stampede Pass. (The National Weather Summary)
