WEATHER BLOG: Saturday

Yesterday was a nice day, with the high at BWI reaching 83. Currently, a backdoor front is approaching the area. It has passed through eastern Long Island and the immediate Jersey Shore and areas out there are into the 40s and 50s already. This front will continue to press toward the city early this morning. This will lead to fog and clouds this morning and a light easterly flow. Temperatures today will be cooler with that flow along the coast, but still getting to near 80 in the city and westward. Fog and low clouds will give way to sunshine during the afternoon. Along the coast, it may take until early afternoon to clear out with a stronger marine influence.

By Sunday, a 500mb ridge will crest over the east coast and this will lead to a southwesterly flow and warmer conditions (mid 80s likely) Meanwhile, subtropical storm Ana will impact the Carolinas. This will impact our weather somewhat early next week with a bit more moisture to work with as a front approaches.

By Monday, a cold front will begin to press toward the region. Given the instability and forcing in place, there will be some showers and thunderstorms around, especially during the afternoon. It will be warm once again, into the mid to upper 80s. The front will inch closer Tuesday, and in a prefrontal environment, this will likely be our warmest day of this stretch- into the upper 80s! The front will move through Tuesday night, and refreshing air will follow for the rest of the week as a large area of high pressure takes over.
