Warm again Tuesday before we get a dose of December reality.
The next few days are expected to bring dry weather to the Mid-Atlantic States. Even though a front managed to push through Maryland Wednesday evening (and northwest winds between 8 and 10 p.m. gusted to between 20 and 30 mph), it didn’t bring any widespread clouds or showers.
Well, so much for my idea of Thursday being dry.
What a beautiful day, weather-wise. Sunshine has filled the sky, combining with low humidity/dew points for a wonderful afternoon.
The overall feeling is that warming aloft should limit coverage of showers and thunderstorms to a rather small fraction of the area Friday and over the weekend. But there will continue to be plenty of moisture in the air so we would not want to totally rule out a thunderstorm on any given day.
Tuesday morning’s front left little in the way of rainfall. However, it did leave us in a much different air mass Tuesday afternoon.
The warm air is going to stick around as highs go back to near 70 degrees again Wednesday afternoon. However, there is a cold front that will be going through at the same time.
The recent rain has ended, but the regional radar is still showing an isolated shower in spots early Thursday. Total rain at BWI-Marshall amounted to about 1.55,” eating into our deficit for the year.
An upper-air disturbance has been hanging back to the west today, even though it’s trying to clear the coast. The cold air aloft has still helped to trigger a shower and brief downpour in parts of the area this afternoon.
High pressure has nosed itself down from the north, promoting a dry day across the region with some sunshine. As high pressure shifts eastward, the wind flow will turn more southwesterly tonight and tomorrow increasing the humidity ahead of the next storm system.
The showers and thunderstorms that were fairly widespread yesterday/early last night have pretty much wrapped up now.
After a warm, beautiful day with very low humidity yesterday, we had a repeat today. A small cluster of thunderstorms did develop over southern PA that have drifted into Washington and Allegany counties this afternoon/evening.
