.DISCUSSION...
KEY MESSAGE 1: Hottest temperatures of the year so far forecast
early next week
An anomalous upper ridge building over the east-central U.S.
will deliver summerlike conditions over the weekend through the
first part of next week. Max temps are on track to peak in the
mid 80s to lower 90s Monday and Tuesday and could challenge
daily records in some locations. Manual adjustments were made
to lower NBM maxT by a few degrees due to a known systematic
bias correction issue identified during the shoulder seasons.
This should also keep max heat indices under 100F for the most
part. However, heat risk impacts will continue to be monitored
given the quick ramp-up in heat and limited acclimation time.
A cold front accompanied by showers/t-storms brings relief next
Wednesday into Thursday. Temperatures are forecast to cool down
back to historical/climo averages for late May for the end of
next week.
&&
.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions expected tonight with decreasing clouds and
wind with sky expected to be mostly clear for most sites after
midnight. Clouds overspread much of PA throughout the afternoon
Saturday but VFR likely continues for most of the day. Sct
showers with some isolated thunderstorms possible mainly over
the western airfields from late afternoon into early Saturday
night.
Outlook...
Sat-Sat Night...Chance of showers/isolated t-storm mainly over
the western terminals.
Sun-Tue...Mainly VFR. Patchy A.M. fog. Isolated P.M. shower or
t-storm possible.
Wed...Restrictions probable through Wednesday night with
showers/storms along CFROPA.
