PM Update: Another heat wave beginning
Hot and humid for near future; Weekend rain threat?
Highs reaching the low-to-mid 90s today are accompanied by fairly uncomfortable dew points in the mid-and-upper 60s. This combination is creating heat indices about 5 degrees higher than the apparent temperature. So, after a bit of a break, it's pretty hot again. As readers of CWG know, today is the 32nd day of the year at or above 90 in D.C. While it looks like we've got a good number more ahead of us in the coming period, with so many behind us already we must be at least half way done... Right?!
Through Tonight: Watch out for a very isolated shower the rest of the afternoon into evening. Otherwise, another mild and muggy evening is ahead as temperatures fall toward the upper 80s around sunset. Skies are mostly clear through the night with readings falling to around 70 in the suburbs to the mid-70s downtown.
Tomorrow (Friday): We turn up the heat another notch tomorrow under full sunshine and a still humid air mass. Temperatures approaching or past 90 by lunchtime should top out mainly in the mid-90s with a few upper 90s possible. Winds should be light from the southwest.
Drought watch: Despite the multiple rounds of rain, today's update of the "Drought Monitor" kept the area in moderate drought. While it does not include rain that fell after Tuesday morning, it gives a general sense that the area will likely not lose the dry factor entirely unless we get more rain. Drought conditions also expanded north into New Jersey and parts of Pennsylvania. A small evening shower yesterday pushed D.C.'s 6-day total (ending yesterday) to 3.79", the same amount that fell over the 53 days prior to that.
