Synopsis
A frontal boundary will remain in the vicinity of pennsylvania
through Monday. This will bring widespread showers and
thunderstorms to the region for the next day. High pressure
will build southeast into the region for the middle of next week
bringing slightly cooler temperatures and lower humidity
levels.

Near term until 7 am Sunday morning
Three distinct cluster of showers running through the area
right now. Storms over the laurels contain heavy rain, but it
has hardly rained there today, so flooding worries low there for
the evening and early tonight. Rain and spinning showers moving
out of the eastern counties are very low-topped and produced
little if any thunder as they passed through, but did make a >2"
rain stripe from penfield to lock haven. One spotter in lock
haven had almost 2.5". Much of the area is just soaking in this
largely beneficial rain. Tweaks made to pops for the next few
hours based on recent radar and cams trends.

Prev...

complicated forecast for next day. MCS moving across cwa
currently has lost a lot of its intensity over our area. Still
a couple areas of heavy rain though. One area across mifflin
county moving fast enough NE and is rather benign. Gages in
mifflin showing around a half to three quarters of an inch.

Another east-west band is entering western clearfield county.

Cams have been showing some heavier rainfall totals as this is
forecast to pivot NE and eventually slow down. Elsewhere radar
returns show only light showers. With high pw air and frontal
boundary over the area, models show more development this
afternoon and evening across the southern 2 3 of the cwa. Low
level jet will also increase overnight. Will keep pops high to
cover this. Still can't rule out a few stronger storms across
the south. Storms will also have brief heavy downpours with a
quick 1-2 inches of rain possible. So isolated flooding is
possible as well.

Short term 7 am Sunday morning through Sunday night
More convection is likely on Sunday with frontal boundary moving
little overnight. Moderate capes and moderate westerly flow
aloft, combined with large scale forcing ahead of approaching
upper trough, should support widespread convection by afternoon.

Long term Monday through Saturday
Looking at some dry weather for a change from later Monday
into wed, as weak high pressure builds into the area.

Less humid and slightly cooler weather for mid week.

Some showers and storms on Thursday into early Friday, as
another cold front moves across the area.

Back to dry conditions by later Friday into the weekend.

Cut back on showers and storms for Wednesday night and later
Friday.

Aviation 04z Sunday through Thursday
Storms have moved through and exited the region. Rain continues
through the NW at bfd. The clearing skies will give way to low
ifr across the region so expect ifr CIGS to develop over the
next few hours between 04z to 06z. At bfd there is the potential
that CIGS drop to ifr and lower and then drop to the valley
between 08z to 10z. Otherwise ifr restrictions across the region
will continue until shortly after sunrise.

Another round of severe weather will move through the region
Sunday afternoon.

Outlook
Sun night... Cig restrictions likely. Scattered tsra shra.

Mon... Am restrictions likely. Scattered tsra.

Tue-wed... Patchy am fog. Otherwise no sig wx.

Thu... Chance of showers and storms.

Ctp watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
