It looks like the overall dry weather pattern of recent days in the Mid-Atlantic region will continue through the work week, but the holiday weekend could turn out to be somewhat unsettled as an upper-level low might move to a nearby position. High pressure will maintain control of the weather through mid-week providing us with dry conditions and comfortable temperatures and humidity levels. The passage of a cool front on Wednesday evening will usher in a bit cooler air mass for Thursday and Friday, but it should remain dry.

It turns a bit milder today in the Mid-Atlantic region as high pressure pushes off the eastern seaboard. Low pressure will form along the east coast later tonight and, at the same time, a frontal system will close in on the eastern states from the Midwest. The combination of the two systems will bring us plenty of cloudiness and occasional showers will be possible from later tonight into the PM hours on Saturday. High pressure is expected to return for the second half of the weekend bringing us plenty of sunshine on Sunday along with comfortably warm conditions.

The chilly and dry air mass that moved into the Mid-Atlantic region following the passage of a cold front will help to keep temperatures at below-normal levels for another day despite plenty of sunshine. It turns somewhat milder on Friday and low pressure will try to organize near the east coast at the same time a frontal system pushes this way from the Midwest. The combination of the two systems can result in shower activity around here on Friday night and Saturday. High pressure is to return for the second half of the weekend with sunshine expected on Sunday.

The next couple of days will be quite stressful for tender and newly planted vegetation in the Mid-Atlantic/Northeast US given the double whammy of possible frost/freeze conditions and the influx of an excessively dry air mass. This is quite late in the season for a possible frost/freeze; especially, in the Mid-Atlantic region, but indeed that is on the table for late tonight/early tomorrow across interior sections of the northeastern states. This unusually chilly air mass for this time of year is also one that is very dry and dew points will drop into the 20’s over the next few hours.

A cold front passed through the region early this morning and today will turn out to be a breezy and cooler day than yesterday with temperatures likely peaking around the 70 degree mark. Temperatures should drop into the lower 40’s late tonight under clear skies and it is not out of the question that some outlying spots experience a late season patchy frost towards daybreak. After another cool day on Thursday, it turns milder at week’s end and weak low pressure combined with a frontal system can produce some showers here on Friday night or Saturday. High pressure resumes control of the weather for the second half of the weekend.

Canadian-born high pressure to our north will expand into the region on Wednesday and we’ll turn cooler with breezy conditions as well. It stays dry and on the cool side for Thursday with milder weather coming back to close out the week as the same high pressure system exits off the east coast.

The central third of the nation will be the part of the country with the most rainfall in coming days and also the highest likelihood for severe weather. An area of focus for the rainfall will be the state of Texas with a big concern for excessive amounts in the Texas/Mexico Rio Grande border region. Severe weather including isolated tornadoes is a threat today from Kansas-to-Oklahoma and to the east of there across Louisiana, Arkansas and Mississippi. Severe weather will remain as a threat in the same (central) part of the nation in coming days as well.
