Weekly Weather Outlook
By: Paul Knight, Pennsylvania State Climatologist - 05/28/2014
Very warm and humid conditions will dominate the western half of the state on Wednesday as cooler, slightly drier air pushes into the eastern counties. Along the boundary, a few thundershowers are likely.
High pressure forming over the Canadian Maritimes should push the boundary with warm, sticky weather to the southwest and eventually out of the state late on Thursday, though a few thundershowers are likely in the central or southern counties on Thursday. A reinforcement of somewhat cooler air will arrive on
Friday with clearing skies.
Cool, dry weather will mark the transition from May to June with a stray afternoon shower in the northeast counties on Saturday.
A marked warm spell will develop either Sunday or Monday and continue at least until Tuesday and probably Wednesday with a few readings (mostly in the southeast) reaching 90F. Another push of cooler air from Canada is likely at mid-week preceded by some thunderstorms, a few could be severe.
The end of next week (June 5-8) may produce a couple of unsettled days as a front stalls not too far south of the state. This general pattern of several increasingly warm days interrupted by cooler, drier air should continue into mid-June.
There are some indications that an early season tropical storm may affect the Gulf region during the latter half of June.
