Area forecast discussion, Mar 30, 9:16 PM EDT, 54 minutes before

Area Forecast Discussion
National Weather Service Wilmington OH
916 PM EDT Thu Mar 30 2017

.SYNOPSIS...
Showers and thunderstorms can be expected tonight, as a low
pressure system and its associated cold front move through the
Ohio Valley. The low will move slowly off to the east on Friday,
with some showers lingering on its backside. High pressure will
offer dry weather and cooler temperatures for this weekend.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
Severe threat has rapidly diminish across the region given loss
of instability and and outflow boundary pushing into our western
zones. Showers and embedded thunderstorms are still expected
overnight ahead of a cold front. However, severe weather is not
anticipated. Some locally heavy rain will be possible where
thunderstorms persist. Temperatures will fall into the lower
to mid 50s by sunrise Friday as the frontal boundary works its
way east.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
Surface and upper level closed low will be occluding on Friday,
slowly pushing east to a position off the lower New England/mid
Atlantic Coast by Friday night. Showers will be likely early on
in our far east, with a lingering threat for showers across the
remainder of the region until the center of the upper level low
pulls sufficiently away. With mainly cloudy skies and some CAA,
temperatures will not warm all that much from the morning lows.
Highs will range from the mid 50s west to near 60 east.

Clouds will linger into Friday night while the threat for
lingering showers tapers off from west to east. It will be cool
with lows dropping into the upper 30s to the lower 40s.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Extended period begins with the region in the wake of a departing H5
low. H5 ridge and sfc high will build in for Saturday bringing
cloudy but dry conditions. Highs will range from the upper 40s to
mid 50s. The dry weather will continue into Sunday. Temperatures
will rebound into the upper 50s to mid 60s.

Models begin to show their differences by late Sunday as another
system ejects out of Texas. The GFS is the weakest and slowest with
the system as it moves to east of the MS River. The ECMWF and CMCnh
are quicker and stronger. Continued with high chance of rain across
the fa, especially in the south. Kept a chance of thunder for the
southern sections also.

The system pulls east Monday night, leaving the region dry for
Tuesday. Another upper low swings out of the central plains on
Wednesday, bringing another chance of showers and thunderstorms for
the later half of the week.

&&

.AVIATION /01Z FRIDAY THROUGH TUESDAY/...
Low pressure and its associated cold front will move east into
the Great Lakes and Ohio Valley through the tonight. As it does,
showers and thunderstorms will be on the increase, with the
highest threat for precipitation coming in the 02Z to 09Z time
frame as a semi cluster/linear feature works its way east across
the terminals. Depending on the location at this given time,
either TEMPO thunder or VCTS has been used. Aviators can
expect MVFR conditions in thunderstorms. Atmosphere will be
conducive to locally heavy rain/IFR visibilities in
thunderstorms, but this will have to be handled in a short term
TEMPO as the system starts to evolve. Gusty winds this
afternoon will decouple and become more stable by this evening.

On Friday, an upper level closed low will move east across the
Ohio Valley, with substantial instability having moved east
with the cold front. Some lingering showers east and spotty
showers west are expected with the upper level low. Ceilings
will be firmly in the MVFR lower category, i.e. in the 1000 to
2000 foot range.

For Friday night, upper level low will continue to move to the
mid Atlantic/southern New England coast. Shower threat will
taper of but low ceilings will remain in the MVFR/IFR category.

OUTLOOK...MVFR to IFR ceilings likely Friday night into
Saturday. MVFR ceilings and visbilities possible Monday into
Tuesday.
