Area Forecast Discussion National Weather Service State College PA 723 AM EDT Tue Aug 4 2020

SYNOPSIS. A corridor of steady moderate to heavy, and in some cases excessive rainfall associated with tropical storm Isaias is expected across eastern Pennsylvania through this afternoon. As the storms heads steadily northeast toward the New England states late today, conditions will dry out for tonight into Wednesday. Scattered showers and thunderstorms return to the forecast by late in the week. Temperatures will dip below average on Tuesday before trending warmer later in the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. An extensive plume of Tropical moisture streaming north ahead of Isaias (that is now near Norfolk, VA), combined with weak low level FGEN forcing under the right entrance region of an upper level jet, will produce steady, moderate rain into late this morning.

As the SE LLVL flow strengthens, taps LLVL moisture and lifts it into the strong mid level FGEN/deformation region just to the west of Isaias's track (and at the nose of the highly anomalous/5-6 sigma v-wind), rainfall intensity will increase to between 0.5-0.75" per hour for several hours late this morning through mid afternoon along and to the east of the I-83/I-81 corridors. This is where WPC raised their excessive rain threat to the High Risk category - with storm total rainfall of 3-5 inches.

There will be an extremely sharp east to west rainfall gradient within about 30 miles west of Middle and Lower Susq mainstem and very little rainfall is expected to the west of the I-99/RT 220/15 corridor per the latest 08Z HRRR.

A Flash Flood Watch remains in effect for this area. Lower Susq tribs to the east of Harrisburg appear to be most susceptible to minor flooding at this time. Fortunately, progressing through the first half of this event with relatively dry ground in most places

- although the eastern part of the CWA has been the "wettest" relative to moderate drought locations in the central and western parts of the CWA. Antecedent conditions are a big factor when considering potential flooding impacts.

Sustained winds and gusts across the far southeast zones incorporating guidance from NHC and high res CAMS, are slightly higher than previous fcst but just under wind advisory criteria across Lancaster County.

A fairly moist WNW upslope flow over the Western Mtns will support plenty of thick strato cu and some light showers, but total QPF should be in the one to two tenths of an inch range.

High temps today will be mainly in the 70s, though a few locations near I-81 in the southern tier of PA could see the mercury peak at 80 or 81F.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/. A few lingering showers will occur tonight, mainly over the western mtns of the state.

The lingering effects/runoff of the prior rainfall may be making flooding of larger streams and creek over the ern locations on Wed. However, much if not all of any flooding should be receding by Wed night.

Large picture starts with a slight trough with axis over the OH Valley. The upper pattern should then turn more zonal for most of the period but with a couple of small amplitude waves rolling through. Dry high pressure at the sfc will provide a mainly dry weather Wed-Thu as it sits overhead or just to our north.

A weak wave of low pressure riding along stalled front to our south will produce a small chc of showers over the srn tier on Thursday. However, it will be light stuff, and no worries for any renewed flooding.

LONG TERM /FRIDAY THROUGH MONDAY/. GEFS plumes indicate the best chance of rain in the extended forecast will come Friday, when all guidance tracks a decent shortwave east from the Grt Lks. Current forecast calls for around a 50pct chance of PM showers/tstorms based on latest NBM/Superblend. The bulk of medium range guidance supports drier weather next weekend, as shortwave exits the state and surface high pressure builds in.

Expect near seasonal temperatures Friday-Saturday, then a return to above normal readings appears likely toward the end of the long term, as surface high passes off the coast and return southwest flow ensues. Have also introduced an increased chance of diurnal convection by Monday, as higher pwats arrive on southwest flow.

AVIATION /12Z TUESDAY THROUGH SATURDAY/. Conditions starting to come down at times across the central and western areas as light rain has started.

Earlier discussion below.

As of 6 AM, rain and lower clouds starting to work into western areas.

Overall looking at wet day, with CIGS lowering some.

The morning rain has developed ahead of approaching Isaias, with its impacts peaking during a several hour period midday today as center of storm slides up across Delmarva, near PHI and into NJ. Rain, locally quite heavy will impact eastern third of CWA with continuing restrictions. Central and western areas will see some improvement late morning with lighter, more scattered rain activity as one heads further westward. Mentioned gusty winds across the southeast airfields Tue, with winds diminishing by later in the afternoon.

Outlook .

Wed-Thu . Trending drier/VFR with just an isolated shower or t-storm possible.

Fri-Sat . Local impacts from sct showers/tstms.
