215 am edt Wed mar 20 2019

Near term [through today]
Nearly zonal flow aloft with weak high pressure and a dry airmass in
the lower levels. High temps will be a few degrees warmer than what
we saw on Tuesday mainly due to less cloud cover. Highs will range
from the upper 60s to lower 70s.

Short term [tonight through Friday night]
An upper low starts to move through the great lakes tonight with a
cold front draping south through ms. The upper low and surface low
are weak so as the front moves east on Thursday, it will weaken with
all precip staying north of the region. An increase of clouds in se
al and SW ga is the only thing we will see locally. Winds however
will shift to the northwest Thursday night behind the front. Surface
high pressure builds in for Friday with dry weather continuing.

Highs Thursday will be similar to Wednesday, in the upper 60s to
lower 70s. Even with the northwest flow, rising heights will start a
warming trend with highs Friday a degree or two warmer. Lows will
remain in the mid 40s.

Long term [Saturday through Wednesday]
A mid and upper level ridge continue to build over the area
through the weekend with surface high pressure and dry weather
continuing. Highs Sat will be in the lower to mid 70s and with
southerly flow returning on Sunday, highs will warm Sunday and
Monday into the upper 70s. The next upper trough will be moving
east on Monday with a frontal boundary extending from maine all
the way south through texas with weak surface lows developing
along it. Clouds will increase on Monday ahead of it. The GFS has
a more progressive system and a stronger upper level jet streak.

This will push rain into the region by late Monday afternoon while
the ECMWF holds off until after midnight. The GFS also moves
everything through quickly while the ECMWF develops an additional
upper level trough and surface feature, continuing rain through
Wednesday. Will keep a chance pop in for this time frame to
account for uncertainty.

Blended guidance is taking more of a GFS approach with winds turning
northerly behind the initial front. Tuesdays highs with the rain and
clouds will be in the upper 60s to mid 70s and dropping Wednesday
into the 60s. Lows will warm into the 50s for the weekend ahead of
the front and drop back to the 40s behind it.

Aviation
[through 06z Thursday]
vfr conditions will prevail through the period with light north to
northeast winds.

Marine
A small craft advisory remains in effect for portions of the
northern gulf waters through 10am edt. Latest buoy observations
shows winds are still above 20kts so will not make any changes to
the advisory. Winds and seas will slowly diminish through the
day. Winds shift to the northwest on Thursday and increase again
to around 20kts. Otherwise, winds remain 15 knots or less and seas
will remain around 2 to 3 feet.

Fire weather
Minimum relative humidity values will drop near or below 30 percent
this afternoon and again Thursday afternoon. However, aside from
high dispersion values expected on Thursday, red flag conditions
will not be met due to light wind and elevated fuel moisture.

Hydrology
Dry weather is expected through the weekend. The next chance of
rain will be Monday through Wednesday with rainfall amounts
forecast to remain below half an inch. Flooding is not expected.

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.
