(EXTRACTED FROM FXUS61 KPHI 212040)
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Rest of this afternoon...VFR ceilings, with localized MVFR ceilings
at times (cloud bases between 2,500-5,000 feet). Southwesterly winds
around 5 knots.
Tonight...VFR (marginal MVFR) ceilings lower to MVFR, then to near
IFR overnight. The lowest ceilings are anticipated for RDG, ABE and
TTN where especially some light rain, drizzle and fog will also be
possible. Low confidence however regarding the ceilings. Southerly
winds less than 5 knots or light and variable.
Monday...Sub-VFR conditions improve to VFR from south to north
through early afternoon. Some light rain, drizzle and/or fog is
possible in the morning, especially north and west of PHL. Lower
confidence regarding the ceilings. Light and variable to southerly
winds less than 10 knots.
Monday night...conditions lowering to IFR or less with low ceilings
and visibility restrictions due to rain. Southerly winds of 10 to 15
kt are expected. A period of low level wind shear (LLWS) is likely
to develop late Monday night as a strong low level southerly jet
develops, though exact timing and location of the jet is uncertain
Tuesday...Starting IFR or lower Tuesday morning, but improving to
VFR conditions behind a cold front expected during the day Tuesday.
Also expect an abrupt wind shift from southerly to westerly winds
with the cold front. Wind speeds of 10 to 20 kt with higher gusts
will be possible especially just behind the cold front. LLWS
conditions may linger into Tuesday morning along the coastal plains.
Timing of the front, and consequently improving conditions is
uncertain at this time.
Tuesday night through Friday...VFR conditions expected. Westerly or
northwesterly winds less than 15 kt. Gusts above 20 kt possible
during the day Wednesday and Thursday. High confidence.
