It’s been a day of many weather types around the region. First we saw briefly heavy rain this morning along with embedded thunder, and that was followed by a pretty gray midday. The sun finally made some inroads (particularly D.C. area and southwest) as the afternoon has progressed, but places nearer Baltimore are still stuck around 60 degrees. A warm front is draped almost right over D.C. as the much anticipated cold front approaches from the west.
Through Tonight: While the heaviest and most consistent rains are long done, we may still see a brief shower or t’storm (30% chance) as the cold front moves through this evening. It’s even possible, given strong wind shear aloft, that one or two storms could become strong. This activity should be outta here by around or just after sunset though, and immediately followed by cooler breezes from the northwest as well as clearing skies. Lows eventually reach the mid-40s to near 50.
The weekend: Perfect? Both days feature lots of sun — Saturday perhaps cloudier on the whole but only partly cloudy at worst. Daytime temperatures range from about 62-68 Saturday and Sunday, with mostly light breezes that may be briefly gusty Saturday afternoon. Overnight lows Saturday night are in the 40s. Might be worth keeping an eye out for aurora as well, even locally.
Sandy: We’ll never see the name Sandy used again when it comes to tropical systems. The World Meteorological Organization decided to retire the name due to the major impacts seen in the Caribbean and the Mid-Atlantic to northeast United States.
Pollen update: Heavy rain overnight into this morning washed out the latest pollen count. Tree pollen will climb back to HIGH as the sun returns, with Oaks really starting to factor in (Oaks are usually the big player locally for tree pollen). Grasses and weeds should start to rise as well.
