1042 am edt Mon mar 18 2019

Update
The forecast for today is in good shape, with no updates
necessary.

Prev discussion [641 am edt]
Near term [through today]
High level moisture will stream across the region today in
association with the subtropical jet stream. The clouds will
likely thicken up a little from west to east as the day GOES along
and remain the most opaque over far southern sections. A little
more filtered sunshine than yesterday should yield temperatures a
couple degrees warmer across the board.

Short term [tonight through Wednesday]
High level cloudiness should thin exit by Tuesday morning followed
by partly to mostly clear skies through Wednesday. The very dry
atmosphere will yield cool mornings and comfortably warm
afternoons across the area.

Long term [Wednesday night through Monday]
A strong short wave will come over the top of an upper ridge over
western canada and dive southeast toward the area on Thursday
before shearing to our north Friday. This will have little effect
on our weather other than to bring a few clouds and help increase
the pressure gradient a bit. Next rain chance still looks to be
late in the weekend into next week as a southern stream short wave
approaches. Blended guidance temperatures look pretty good and
will feature a steady warming trend through the period.

Aviation
[through 12z Tuesday]
some MVFR fog has formed around vld this morning. Fog should burn
off by 14z or so leavingVFR conditions through Tuesday morning.

Vfr conditions expected at the other terminals throughout.

Marine
Northerly winds will be above cautionary levels at times today
especially well offshore. Winds may pick up to advisory levels for
a time tonight into early Tuesday before decreasing again.

Fire weather
High dispersions are likely both today and Tuesday due to a
combination of elevated mixing heights and transport winds.

Afternoon rh values will be quite low however red flag conditions
are not anticipated due to light winds and elevated available
fuel moisture.

Hydrology
No flooding is occuring or anticipated for the next several days.

Our next chance for measurable precipitation will be early next
week.

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.
