- Hydrometeorological Prediction Center's rainfall forecast through Wednesday
The weather pattern this week has Fall written all over it as temperatures and conditions will be wide ranging. The focus for the first half of the week will be mild temperatures and rain. We're expecting highs in the 60s Monday through Wednesday, which will be five to ten degrees above average for this time of year. However, in typical spring fashion our temperatures will take a tumble with highs back down to near 50 degrees by Thursday and Friday despite vast sunshine. By the way the average high at Reagan National Airport (DCA) is 59 degrees today.
In terms of rain, a series of cold fronts and upper level energy will help cause the showers, and as of now, it looks like the heaviest rain will hold off until Wednesday morning. However, a few showers are expected in the mountains/west of I-81 today. Isolated rain is also in the works for Tuesday as well, but the most organized and widespread rain is set for Wednesday when everyone should get some of the action. Accumulations should be on the order of 1-2 inches by Wednesday evening when the rain comes to a halt (see above image). Stay tuned to abc7 for updates to this forecast.
We all know that there hasn't been a shortage of rain over the past three months, but November has thus far been running below average for precipitation at DCA with totals 1.30 inches below normal. That said, our year-to-date precipitation is still 5.23 inches above average. The rainfall this week should get November back on track for rainfall across the metro area.
