area forecast discussion
national weather service tallahassee fl
635 am edt Tue mar 26 2019

Aviation
[through 12z Wednesday] pockets of low ceilings and patchy fog
across the area will dissipate by 13-14z. MainlyVFR is expected
from mid-morning through the daytime hours. By this evening,
showers and lower ceilings with MVFR conditions are expected to
spread from north to south across mainly aby, tlh, and vld,
although dhn will be close to the western edge.

Prev discussion [315 am edt]
Near term [through today]
Another interesting forecast is shaping up over the next 24 hours.

Expect showers and possibly a few thunderstorms to spread across
portions of the area this evening with small hail a possibility.

However, most of today will remain dry. Afternoon highs will range
from the mid 60s to mid 70s across the area with overnight lows in
the mid 40s to low 50s.

Currently, a rather strong shortwave is evident on water vapor
imagery over eastern kansas, moving quickly southeastward. This
feature will move right over the forecast area tonight. At the
surface, an inverted trough will bisect the forecast area with low
level moisture actually advecting into the area from the northeast,
which is a bit unusual. In addition, with the upper low moving right
over the area, 500 mb temperatures will dip to climatologically low
levels, down to the -22c to -24c level in the 03-06z range tonight,
which are near record daily minimums for this time of year. These
cold temperatures aloft will steepen the mid-level lapse rates
considerably with 700-500 mb lapse rates forecast to exceed 7c km.

With sufficient deep layer shear, don't be surprised to see a few
thunderstorms this evening, and with such cold temperatures aloft,
small hail appears possible with some of the storms this evening and
overnight.

Short term [tonight through Thursday]
Quiet and pleasant weather will persist through the short term
period as northwesterly flow persists in the wake of the upper level
shortwave trough departing the florida east coast Wednesday morning.

Temperatures will generally run several degrees below normal through
the period, with a moderating trend toward the latter part of the
week. Expect highs in the 60s and 70s and lows in the 40s.

Long term [Thursday night through Tuesday]
Upper level flow will become quasi-zonal across the region on
Friday, as a series of shortwave troughs approach from the west.

The first wave will traverse the tri-state area on Friday
night early Saturday morning, bringing little notable weather
outside of an increase in cloud cover. A potent low over the
hudson bay will eject a second, stronger shortwave trough across
the ohio valley late Saturday into Sunday that will push showers
into our area on Sunday. Guidance is consistent in a third
shortwave trough upper low developing in the inter-mountain west
and splitting the jetstream into two branches. Timing of this
feature moving through the tri- state area is generally early next
week, during the Monday Tuesday timeframe. However, operational
guidance remains inconsistent from model to model and from run to
run regarding the strength and timing of this system. Nonetheless,
expect a return to wet weather early next week.

Expect warm temperatures this weekend to give way to cooler
conditions early next week.

Marine
Winds and seas will increase today with the approach of another
system from the northwest. Expect at least cautionary conditions by
this evening, with a period of advisory level conditions overnight
into Wednesday morning. Winds and seas will gradually decrease
through Wednesday afternoon, with offshore areas potentially seeing
cautionary conditions persisting into Wednesday night. Calmer
conditions will persist Thursday into the weekend.

Fire weather
A much drier airmass will move into the area on Wednesday with
relative humidity values dropping to critical levels across a large
portion of the area. If the winds end up slightly higher than
currently forecast, then red flag conditions could occur across
portions of the florida panhandle and big bend on Wednesday
afternoon.

Hydrology
All rivers remain below flood stage at this time. No significant
rainfall is expected through the next week with rainfall totals
remaining below 1 inch. Therefore, rivers are expected to remain
below flood stage.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
