Fire Weather Planning Forecast for Central Pennsylvania

.DISCUSSION...
Periods of showers and a few thunderstorms are expected this
afternoon into tonight. Some of the storms could become severe
with localized damaging wind gusts and heavy rainfall, mainly
east of the Susquehanna Valley and possibly into the Laurel
Highlands.
Much of Central PA is under a cloudy and more stable airmass from
extensive cloud cover resulting from a fairly lareg area of mid
to late morning showers and thunderstorms across Western PA.
A relatively cooler and noticeably less humid airmass arrives
through midweek followed by a stretch of dry weather into the
weekend.
