405 AM EDT Wed Jul 20 2022
A weak ridge of high pressure will hold through today.
A cold front will cross the region Thursday night. This
boundary stalls to the south before returning northward as a
warm front by early in the weekend. Strong ridging builds over
the region this weekend and into early next week.
.NEAR TERM /THROUGH TONIGHT/…
Ridging will hold through today and this will help supress
convection. It will be hot with highs in the mid 90s or about 5
degs warmer than yesterday. Warm and muggy tonight with lows in
the mid 70s. A few showers may approach the Appalachian region
very late tonight, but most likely will hold until Thu.
.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/…
Mid-upper level trough over the Great Lks will cross the area
Thursday afternoon. Latest model guidance is a bit more
optimistic with convective potential Thu afternoon showing sct
convection developing mainly east of I-95 across southern MD.
However, the strongest signal for convection continues to be
south of our area over AKQ`s CWA. Any convection should exit the
area by 00Z Fri. Remaining hot Thu through the weekend with
highs at least in the mid 90s. Heat indices Thu will be just shy
of advisory criteria and remain below 100F due to much lower
.LONG TERM /SATURDAY THROUGH TUESDAY/…
H5 heights will continue to rise Saturday into Sunday with westerly
flow developing as a large ridge builds from the central plains into
the SE US. Convection should largely remain suppressed, with the
exception being perhaps a storm in a terrain circulation. H5 heights
peak between 591-594 mb Sunday, with 850 mb, 925 mb, and sfc temps
maxing out Sunday as well. Slight chance POPs Sunday north of I-68/I-
70 as some guidance suggests a thunderstorm complex moves across
Pennsylvania, though low confidence at this time. Heights lower
slightly into Monday as a shortwave and associated sfc cold front
move through, hence POPs increase as a weak shortwave moves through
in the embedded west/northwest flow. The front will stall in the Mid-
Atlantic into midweek with notably cooler conditions, with near or
above average temps still expected. Diurnally driven
showers/thunderstorms expected into the middle of next week.
The focus through much of the long term will be the increasing heat.
Widespread low to mid 90s are likely Saturday, with mid to upper
90s, perhaps 100 possible across the metros on Sunday. Heat
headlines appear possible Saturday, with even higher probs on
Sunday. 850 mb temps in the low to mid 20s (C) could result in the
warmest temperature since 2016 for some locales. Not much relief is
expected Saturday or Sunday night with lows near 80 east of
.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/…
Hot and mainly dry weather Wed through Fri. Any convection Thu
is likely to stay south of the terminals.
VFR conditions are expected with light flow generally out of the
west/west-southwest Saturday and Sunday.
Winds strengthen tonight into Thu with SCA conditions likely.
Risk of t-storms Thu afternoon across the southern waters may
Light winds out of the west/west-southwest are expected Saturday
into Sunday. A few gusts just below SCA conditions are possible
during the afternoon hours.
