... Canadian high pressure will stretch across the Great Lakes and into the Mid Atlantic through Wednesday. As the high shifts offshore Wednesday night, a warm frontal boundary will approach from the southwest on Thursday. A frontal boundary will linger nearby through much of the weekend.
NEAR TERM /THROUGH TONIGHT/... A canadian high pressure system will build into our region today. Winds will be breezy and out of the northwest with wind guys upwards of 25 mph possible due to a pressure surge behind the cold front that exited our region last night. The breezy conditions will taper off this evening with winds becoming light and variable. Skies will remain mostly clear with a few linger higher clouds this morning mainly over the WV eastern panhandle and western Maryland. Temperatures will run slightly below average today in the low to mid 70s. Temperatures tonight will fall back into the upper 40s to middle 50s under mostly clear skies.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... Canadian high pressure will remain in place over our region through Wednesday afternoon. Skies will remain mostly clear with winds starting out as light out of the north. High pressure will start to shift out of our region to the Northeast as a warm front moves through our area Wednesday evening and into Thursday. Winds will become southerly by Wednesday afternoon and continue into Thursday leading to a warming trend due to warm advection. Temperatures will trend up into the 80s by Thursday. The frontal boundary will stall over or near our region on Thursday. This boundary will have the potential to act as a focus for the formation showers and thunderstorms. The continued southerly flow through Thursday will lead to advection of warm and moist air into our region which will allow CAPE values to increase above 1500 and possibly as high as 3000 in some areas. Models are indicating that this will mainly be a high CAPE and low shear environment. As the boundary will remain stalled over our region, we can't rule out that a few thunderstorms could reach severe thresholds. There remains a lot uncertainty at this time especially on where the front will stall on Thursday.
LONG TERM /FRIDAY THROUGH MONDAY/... Mid to upper level ridging is expected to persist through the first half of the weekend, with mainly dry conditions winning out the bulk of the time. This ridge will break down on Sunday as the flow aloft becomes zonal, then turning cyclonic as a shortwave digs into the northeast. At the surface, a lingering frontal boundary will reside nearby Friday, lifting northward as a warm front on Saturday as low pressure tracks north of the Great Lakes. With strong ridging aloft and surface high pressure anchored over the southeastern states, thinking shower/storm chances will remain in the low end chance category at this time, with any activity focused during peak heating hours in the mountains and our northern zones, both Saturday and Sunday. Not looking like a washout at all at this time, with temperatures running in the 80s both days. A better shot of showers and storms comes Monday as a shortwave trough digs across the Great Lakes and into interior New England as the flow aloft turns cyclonic. At the surface, another frontal boundary will be dropping toward our region, aiding in the initiation of said showers/storms. Will advertise higher end chance POPs Monday and Monday night as a result, with temperatures well into the 80s for Memorial Day.
