PM Update: Temperatures Slow to Rebound

By Capital Weather Gang

* Obama Proclaims Hurricane Week | National Climate Service? *

Yesterday's chilly maritime flow (from the east) has yet to evolve to a more tropical flow (from the south) so temperatures have struggled to highs near 70 under mostly cloudy skies. The sun and warm air aren't too far away with parting of the clouds and low 80s as close by as Richmond. Temperatures should hold fairly steady through the evening commute with some peeks of sun.

Through Tonight: Skies remain partly to mostly cloudy and a stray shower could pop up (20% chance), mainly before 10 p.m., but most of the area will remain dry. Temperatures won't fall very far, so it will be quite mild overnight, with lows in the mid-60s and areas of mist and fog.

Tomorrow (Thursday): That breeze from the south/southeast will finally kick in (we mean it this time) pumping up warm air, boosting highs back to near 80 despite partly to mostly cloudy skies. Late in the afternoon, a cold front moves towards the region, likely setting off showers and thunderstorms -- a few of which could be on the strong side.

I'm glad to see that Bob Ryan was happy with the "sun and blue sky" that he apparently saw. It never got above 64 in NW Montgomery and the grass is still wet.

@MKadyman

It was a really interesting day as the warm front very slowly moved northward. When I looked at observations around 3 p.m., it still in the 60s in metro area, but in the mid-70s in Fredericksburg, and in the low 80s in Richmond. By 4 p.m., the sun started coming out in the southern part of the metro area and DCA had a wind from the south. Temperatures made it up to 71. At 5 p.m., considerable sunshine had made it well into the District (including NW), and temperatures maxed out in the mid-70s (between 5 and 6 p.m.). If you were stuck at 64, the warm air missed you by 15 miles or less.

I miss Bombo.

Jason is correct....the warm front clearly went north through the D.C. area by late afternoon.

I'm surprised that the cool, shallow marine layer held as long as it did.....almost 2 days. That is unusual this late in the spring. I'm not complaining, though......I dislike heat and humidity, and would MUCH rather have it col and damp than hot and damp. It was a nice 2 days.

Yup, the high was 74° (23.3°C); that's mid-70s:
KDCA 272352Z 00000KT 4SM HZ FEW130 OVC250 23/16 A2988 RMK AO2 SLP118 T02280161 10233 20194 55004

And NCDC reports more daily rainfall records for yesterday in VA, WV, NC.

There was a tight gradient, but the high-res analysis shows that low 70s penetrated well into MD by 5 pm.
