SYNOPSIS... A cold front will push east of the region this evening. An upper- level trough will pass through the area Saturday and high pressure will build into the region for Sunday. A reinforcing cold front will pass through the area Monday with high pressure returning for the middle portion of next week.
NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... Cold front is draped along I-95 corridor this afternoon with a narrow line of heavy showers. There is some weak instability, and lightning strikes are observed in northern MD. Overall though, poor lapse rates will limit thunder. Sufficient wind fields are allowing gusts of 30-45 MPH. Behind this line, there is a lull in the winds, although additional showers will remain possible as sufficient deep moisture is associated with a strong upper level trough. Showers should gradually taper off later tonight across eastern parts of the area.
As this trough becomes negatively tilted this evening, low pressure along the front will deepen. Wind fields will increase aloft, and appear sufficient for advisory level winds at the higher elevations. Even at lower elevations, gusts will increase toward 30 MPH. Temperatures will continue to fall behind the front. At the highest elevations, temperatures will be near freezing, and there may be some upslope snow showers late tonight. Some accumulations less than one half inch are possible above 3kft.
SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/... The main story for Saturday will be the winds. The peak may come during the morning hours as mixing increases; however, winds will remain strong through the day at 30-40 MPH. Will have to monitor for advisory level winds across mainly northern portions of the area. The existing advisory for higher elevations may need to be extended into the evening, as low level wind fields are shown to increase again.
There may be some showers across northern parts of the area (and upslope) during the morning, but the atmosphere will be drying by afternoon. Temperatures will be much cooler with highs remaining in the 50s to around 60 in many locations.
Troughing moves to the east Saturday night and Sunday with high pressure south of the area. A dry period is expected with slightly higher temperatures. A reinforcing cold front will approach Sunday night, with a small chance of showers in the highlands.
LONG TERM /MONDAY THROUGH FRIDAY/... A large sprawling area of high pressure will build into the region from the Great Lakes region Monday into Monday night ushering in a reinforcing shot of seasonably cool air. The high will persist through the middle of next week leading to fair and dry conditions with temperatures at or slightly below seasonable normals.
A cold front may approach the region by the end of next week.
