area forecast discussion
national weather service tallahassee fl
1015 am edt Sat apr 20 2019

Update
The axis of the upper trough is moving east across our forecast
area this morning. Some clouds associated with wraparound
moisture is mainly across our northern zones but no rain is
expected.

Prev discussion [641 am edt]
Near term [through today]
In the upper levels a deep trough remains over the southeast. At the
surface the low is moving into the northeast as high pressure starts
to move into the region. Winds will be gusty late this morning
through this afternoon with gusts up to 25 mph possible. Winds will
decrease late this afternoon and evening as the pressure gradient
loosens. Wrap around moisture may bring some lingering clouds
especially in the al and ga counties. Highs today will be in the mid
to upper 60s, a few spots in fl may reach 70.

Short term [tonight through Monday]
Quiet and tranquil conditions will persist through the short term
period with moderating temperatures. Potent upper low responsible
for yesterday's severe weather across the region will continue to
lift poleward Sunday with upper level flow transitioning from
northwesterly to quasi-zonal with high pressure building in at the
surface. Highs will warm each day in response to the upper level
pattern change, with highs in the mid to upper 70s Sunday and upper
70s to low 80s on Monday. Clear skies and direr air will yield large
temperature swings (25 to 30 degrees), allowing temperatures to cool
into the upper 40s to low 50s each night.

Long term [Monday night through Saturday]
A low amplitude ridge will build into the region Tuesday in response
to an upper low digging into the four corners region. This will
bring high temperatures to a few degrees above normal and lows back
to seasonal normals. The aforementioned low will eject out of the
southern rockies by midweek, moving across the southeast during the
latter part of the week. At this time, operational guidance (gfs,
ecmwf, gefs, ec ensemble) generally differ on the timing of the
feature and resultant weather for the tri-state region. Nonetheless,
our next chances of showers and thunderstorms will come during the
late week time period. It is noteworthy that this system continues
to not look as potent as the last 2 recent systems that have
affected the tri-state area. Stay tuned!

Aviation
[through 12z Sunday]
vfr conditions are expected today. Westerly winds will be gusty
mainly in the late morning and afternoon hours. Gusts up to 25 knots
are possible. Winds will decrease by sunset.

Marine
While winds have decreased below gale force levels at this hour,
hazardous conditions will persist for small crafts through the day
Saturday. A small craft advisory remains in effect through this
evening. Winds will decrease below advisory thresholds this
evening with seas gradually decreasing through the overnight
hours. Calmer conditions will resume on Sunday and persist through
at least midweek.

Fire weather
Relative humidity values will stay above critical thresholds today.

These values will be very low tomorrow but by then the winds will be
light, so red flag conditions are not expected. High dispersions
over 75 are expected today.

Hydrology
Coastal flooding has ended along the north florida coast. Dry
weather will persist into the latter part of next week. Therefore,
there are no flooding concerns.

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.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
