DISCUSSION
KEY MESSAGE 1: Pleasant, rain-free dry spell to end May and start June
Continued influx of Canadian air will maintain comfortably dry and very pleasant weather in CPA to end May and start June. Expect temperatures to remain near or slightly below climo through midweek with warm/sunny days, cool/refreshing nights, and low humidity.
-------------------------------------------------------
KEY MESSAGE 2: Summer conditions return into the first weekend of June
Early week East Coast upper trough/closed low near the OBX shifts eastward and allows upper ridge axis to translate downstream from the Upper Midwest through the Great Lakes. This pattern transition will deliver a noticeable warming trend for late week with summer conditions returning into the first weekend of June. Max temps climb above early June climo into the 75-85F range on Thursday followed by widespread 80-90F readings fcst Friday-Sunday. An approaching cold front impinging on a very warm and increasingly more humid airmass will favor an increasing chance for scattered showers/t-storms by Saturday.
AVIATION /12Z SUNDAY THROUGH THURSDAY/
The VFR regime continues with clear skies expected through tonight and into tomorrow. A few clouds (lass than Sat) will pop up over eastern PA and move north to south through the afternoon as another upper level wave passes through. Any cloud bases are expected to remain above VFR criteria.
Sun is expected to see less gustiness than Sat with winds only peaking in the single digits Sun afternoon, likely strongest in the northeast. Wind direction will generally stay between westerly and northerly. Overall good weather for aviation for at least into the first part of next week.
Outlook...
Mon-Thu...VFR with no significant weather expected. Any showers Tue would be light. Any fog very limited.
