I just looked at the latest ensemble forecast model runs for the Euro and others and this storm is looking quite nasty across the Washington Area.  This could be the biggest snowfall at Washington’s Reagan National Airport with 5″ or more looking likely even on the tarmac there. For Washington’s immediate suburbs… this will be a humdinger of a snow storm, similar to the February 21st event, but with more widespread snowfall totals nearing that 8 to 10″ range across our eastern suburbs.  For this reason, I had to make a slight update to my maps.  And to show my appreciation for you, I listed some more precise suburban locations (please share on Facebook).

Conditions during the pre-dawn hours on Thursday will deteriorate rapidly as temperatures plummet from near freezing (2 AM) into the middle to upper 20s by rush hour (5 to 8 AM) and then into the upper teens by the dinner hour (4 to 8 PM). Yes, our high temperature on Thursday will occur at midnight.  The weather pattern is looking like it will shift to a mild one in mid-March.  This could be our last winter storm of the season… let’s enjoy it.  Spring is just around the corner!
