An area of low pressure and strong upper-level disturbance (vorticity max) may deliver some much needed rainfall across the Washington Region late next week. The image above (courtesy Tropical Tidbits) shows the latest GFS model with a 500-mb vorticity max (dark red colors moving from near St. Louis MO, toward the DC Region) possibly approaching our area Thursday into Friday of next week.
The latest HRRR (High Resolution Rapid Refresh) model shows light rain developing into a steadier rain during the day today with the potential for a break in the action this evening.
The following image (courtesy Tropicaltidbits.com) is a “future cast” from now until 11PM this evening.
- Notice steadier rain moving north out of central Virginia into Northern Virginia, DC and Maryland.
