As a cold front passes through the area this morning, much cooler temperatures will follow.
There is a chance of showers and storms with enough instability and convection, however not much moisture associated with, through early Wednesday as this strong cold front moves through. Temperatures prior to the fropa could get up to the humid upper 80s and after breezy and mostly clear mid 50s.
Thursday into Friday will be a bit windy associated with a 'strong cyclonically curved 300 mb jet that is over the Great Lakes into New England' (NWS)... Oh how I miss Zois's Synoptic classes and drawing these closed lows on maps to the point that all the contour lines morphed into one...
I must say, the maps today look to show quite a beautiful synoptic setup.
Generally with this setup, the surface front will allow enough CAA (cold air advection) and a (drier) downsloping flow into the area which will allow some gusting winds and an explanation for one of the reasons, along with a rain deprived Earth for about the past two weeks, is why the National Weather Service has issued a Red Flag Warning through Thursday. A Red Flag Warning is issued when the relative humidity (the amount of water vapor in the air) is low and falling dewpoint (the temperature given to a parcel of 'humid' air must be cooled at a constant pressure for the water to be condensed: think a cold glass of water left outside on a hot day...the condensed water is know as the dew, and the dewpoint is the saturation point) values below 30%, along with gusting winds make up for dry enough air to support fires.
Temperatures this evening will fall to a chilling mid50s with some suburbs falling to the lower 50s this evening. As for Wednesday: Sunny and 75: My ALL time favorite (sunny) weather. The winds will still be gusting about 15-20mph so it will feel a bit cooler but beautiful nevertheless.
