Once again we have made it through another long workweek. With the weekend on the horizon the big question is to if it will rain or not. Our current weather setup suggest lower chances for storms despite the increased mugginess over the past few days. A weak cold frontal boundary continues to drop down from the north and looks to clear the area Thursday night (June 6, 2019). This front will lower humidity while ushering in a powerful high pressure system which will act as a blocking feature for the weekend weather ahead.
At the same time our front will stall off to the south of Maryland holding heat, humidity and tropical moisture that is currently flooding the Mid-South at bay. The moisture will slowly progress north with an area of low pressure that continues to chug out of the lower Mississippi River Valley. High pressure though will remain strong enough with northeasterly flow to hold the front off until about Sunday since this is when the front plus the extra lift from low pressure wins out.
With all that said we get a mostly dry weekend here in Central Maryland. Friday will feature cloudy to mostly cloudy skies with easterly flow off the water. This should keep our temperatures locked into the upper 70s and low 80s as cooler air wedges up against the Blue Ridge Mountains. Saturday we look to get in on a little more sunshine as the winds switch back to the northeast during the afternoon. Unfortunately by Sunday the clouds and humidity will slowly return along with rainfall. Rain should move in by midday Sunday and take us right on through Tuesday morning.
Rain looks to be heavy at times come late Sunday into the day Monday as the front and multiple pieces of energy move on through. Rainfall amounts could topple 1-2" in many spots leading to localized flooding concerns. Most of the rain looks to exit by Wednesday before another stretch of unsettled weather shortly after.
Long range trends over the next 8-14 days beyond the 7 day forecast suggest above average wet weather chances along with below average temperatures leading up to the first day of Summer. As always it looks to be another year of ups and downs so buckle up for the crazy weather ride!!!
