Temperatures will top out mainly in the lower and middle 80s through the remainder of August. It is possible that Baltimore and Washington, DC could see some 90° readings. A fresh shot of Canadian air could arrive to close the month.

Out West, cities such as Flagstaff, Las Vegas, and Phoenix remain on track for their hottest summer on record. Del Rio is in the midst of its record third extreme heat event (Clarke et al., 2014 framework) of the year. However, the heat began to fade in Texas after setting monthly and even all-time records.

Amarillo reached a daily record 105° (old record: 103°, 1922, 1973 and 2011), its 9th consecutive 100° day. That broke the record of 8 days that was set during June 12-19, 1924 and tied during June 22-29, 1998. The previous longest August stretch of 7 consecutive days occurred during August 9-15, 1936.

The ENSO Region 1+2 anomaly was 0.0°C and the Region 3.4 anomaly was -0.1°C for the week centered around August 14. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.33°C and the ENSO Region 3.4 anomaly has averaged +0.05°C. Neutral ENSO conditions will likely evolve into a La Niña event during the fall.

The SOI was +7.46 today.

The preliminary Arctic Oscillation (AO) was +2.548 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 81% probability that New York City will have a cooler than normal August (1991-2020 normal). August will likely finish with a mean temperature near 75.0° (1.1° below normal).

1992 - Hurricane Andrew made landfall in southern Florida at 4:30 AM on this day. The high winds caused catastrophic damage in Florida, with Miami-Dade County cities of Florida City, Homestead, and Cutler Ridge receiving the brunt of the storm. About 63,000 homes were destroyed, and over 101,000 others were damaged. This storm left roughly 175,000 people homeless. As many as 1.4 million people were left without electricity at the height of the storm. In the Everglades, 70,000 acres (280 km2) of trees were knocked down. Additionally, rainfall in Florida was substantial, peaking at 13.98 in (355 mm) in western Miami-Dade County. About $25 billion in damage and 44 fatalities were reported in Florida.

A beautiful day on the NJ Shore yesterday with a light sea breeze developing around 2 pm.  

 

Is there smoke aloft?   Yesterday afternoon the sky had a yellowish hue that I didn't expect with the low dewpoints and good surface visibility.

74 / 60 as humidity and dew pint creeps up.   Warmer today with mid - upper 80s and outside shot of 90 in the warmer spots.  Mon and Tue the same a touch more humid more upper 80s to some low 90s in the warm spots.  Wed hottest day of the week and maybe till next year mid 90s / upper 90s in the warm spot -pending on how clear / sunny it is.  Thu clouds and showers may spoil heatwave for the warmer spots.  Clouds linger into Friday before showers arrive for Labor day weekend Sat.  Euro much warmer than gfs for labor day weekend.  Other wise near normal then warmer beyond as the atlantic ridge builds back into the end of the first week of next momth.

We need rain 

I gave the vegetable garden some water yesterday for the first time since that rainy period that we had. The soil has dried out. We could use some rain this coming week, but obviously we don't want big amounts again after all that flooding that some areas got a week ago.
