.SYNOPSIS...
High pressure is expected through the entire week. Temperatures
will be well above normal to start the week, but a Canadian
high pressure system descends from the north Wednesday to bring
below average temperatures. There is potential for at least
scattered frost in sheltered, and typically colder valleys by
Wednesday night.
&&
.NEAR TERM /THROUGH MONDAY/...
A weak surface high pressure will be over the region today.
After morning valley fog lifts around 10 AM, it will be a warm
and sunny day. High temperatures will be well above normal, with
some of the warmer urban areas reaching the low to mid 80s.
Clear and dry airmass overhead tonight will allow for efficient
radiational cooling as temperatures fall back into the 40s and
low 50s by Monday morning. Monday will be another warm and nice
day with high temperatures a few degrees cooler, but still in
the upper 70s to near 80.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
High pressure will be in control and strengthen over the region.
This will keep all tropical activity well south of central NY
and northeast PA. A Canadian high begins to press down from the
north Monday night. However, highs on Tuesday will still likely
be in the 70s.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Another large and chilly high pressure system builds south
and covers the region through Saturday. This high will keep
prolonged northeast winds over our area through Thursday.
Thursday morning we may see the potential for more frost and
potentially some freezing temperatures in our normally colder
areas, however there is still some uncertainty if winds will
completely decouple overnight to allow frost formation.
Friday and Saturday, the high pressure slowly builds east and
leads to a moderating temperature trend by next weekend.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
The valley fog this morning should burn off by 10AM. Therefore,
expect VFR areawide through the afternoon and evening with SKC
conditions or a few high clouds. Tomorrow night, there will be
potential for more valley fog at ELM.
Outlook...
Monday through Thursday...Mainly VFR, other than typical valley
fog formation especially KELM late each night through dawn each
morning.
