THIS EVENING: Mostly Clear, Mild. Temperatures In The 70s. Winds: S 5 mph.
OVERNIGHT: Mostly Cloudy, Mild. Lo 65. Winds: Light.
WEDNESDAY: Scattered PM T-Storms, Some May Be Strong. Hi 92. Winds: SW 5-15 mph. Gusts to 25 mph.
It took most of the day but low clouds have finally dissipated across the Lower Susquehanna Valley. It’ll stay mild tonight as additional clouds develop late and a light south wind persists.
Wednesday will be a more active day as southwest winds kick up ahead of a cold front. Heat and some humidity will surge north during the afternoon as highs push into the low 90s. The approaching front will result in some scattered afternoon storms, some of which could be strong given adequate shear (shifting of winds with height in the atmosphere) that will be in place.
It appears two rounds of showers and storms could be on the table. One round during the mid-afternoon, which will consist of pop-up storms mainly capable of producing some hail and gusty winds. Another round of more widespread storms could move in for the evening, but any severe threat with that round will depend on how much the atmosphere has been worked over. If we can stay unstable enough, a damaging wind threat may exist with the evening round of storms, especially over our northern and western counties where a slight risk for severe storms has been outlined by the Storm Prediction Center.
Behind the front, lots of sunshine is expected for Thursday as high pressure briefly settles in. It’ll be cooler but still very warm with highs in the mid-80s.
MEMORIAL DAY WEEKEND: The holiday weekend still looks dreary, but mainly the front half. A system will move through Friday, bringing rain by the afternoon which will be steady at times into Friday night. Saturday will start off cloudy and drizzly, but should be dry for the afternoon. Depending on our wind direction for Sunday, the sun should make an appearance but it’ll still be cool with highs struggling to get out of the 60s this weekend. The good news is that Memorial Day still pleasant at this point with sunshine and highs back to near seasonable levels. We should slowly warm back into the upper 70s and low 80s next week!
