PM Update: Cold front brings humidity relief

By Ian Livingston

Warmth persists through the work week

A cold front passing through the area this afternoon will bring an end to the very high humidity of the past two days, but warm conditions are not going anywhere. Lots of clouds throughout the day have helped keep temperatures near 80 most spots though we may still see some clearing before sunset. A few hit-or-miss showers (and maybe a rumble of thunder) are possible this afternoon, mainly ending by early evening.

Through Tonight: Many spots stay dry, but a passing shower or thundershower is possible as the cold front finishes passing through by early evening. Behind the front, winds become from the west and we'll notice a pretty quick drop in humidity -- it should feel considerably drier by late evening. Under variably cloudy skies, temperatures falling through the 70s this evening should end up ranging from the upper 50s to the mid-60s for lows.

Tomorrow (Tuesday): Drier -- if not much cooler -- air continues to filter in tomorrow and we're looking at a mostly sunny and pretty nice one all around. Temperatures quickly climb into the 70s before noon and top out near 80 or into the low 80s during the afternoon. I'm not too concerned about rain threats at this point, but something could pop up in the afternoon, especially southeast of the area. Light winds from the west and northwest.

Weekend flooding: Parts of the South, and in particular Tennessee, saw extremely heavy rain over the weekend into today. In some places the rain was the heaviest ever on record and it has contributed to over a dozen deaths. The University of Wisconsin meteorology department has put together a collection of imagery and explanations as to why the event produced so much rain. One critical factor, a deep feed of moisture from the tropics, can be seen quite well in this loop.

The front is through a good part of the NW section of the area, about on a line from Rockville to Dulles now. Anyone notice the drier winds yet?

Looks ominous in Lanham, MD...and radar shows thunderstorms heading towards arlington....could we perhaps get more thunderstorms than was initially predicted?

Centreville VA Still as humid as a sauna here, with a heavy shower moving thru.

Just behind National Harbor the cooler drier winds have started to become noticeable. Some pretty dark clouds approaching at the moment.

calmer conditions for the most part, now. But the drop in humidity has also stalled for the moment. It will be a slow process..but we will feel a little better each day this week...
