727 pm edt Fri mar 22 2019

Aviation
[through 00z Sunday]
unlimited CIGS will prevail through the period, with the only
potential for reduced vsbys being smoke near tlh. Along the
coast, we're entering the time of year when we see an afternoon
shift in winds with the sea-breeze front. This is seen with
northwestern winds everywhere except our coastal sites, including
ecp. Winds will calm overnight and become more easterly on
Saturday. Another shift to southern winds will be possible at ecp
Saturday afternoon.

Prev discussion [250 pm edt]
Near term [through tonight]
High pressure across the mississippi valley this afternoon will
shift eastward tonight allowing for light, northerly winds
overnight at the surface. As ridging aloft shifts eastward, the
upper level flow will become zonal late tonight. In this pattern,
the dry conditions will continue through the near term. Lows will
drop into the lower to mid 40s tonight.

Short term [Saturday through Sunday night]
The weather will remain quiet through the weekend as high pressure
slides eastward into the atlantic. As this occurs, winds will
become southerly by Sunday with dewpoints and temperatures
increasing. Despite the increasing moisture, precipitation is not
in the forecast through the short term. Highs will be in the mid
to upper 70s with lows in the 40s Saturday night and only falling
into to the low to mid 50s Sunday night.

Long term [Monday through Friday]
A cold front will push into the southeast on Monday and across
the CWA Monday night bringing the chance of precipitation back to
the forecast. The front will be weakening as it moves through and
precipitation amounts will be limited. Behind the front, dry
conditions are expected through the remainder of the week. While
highs will initially be in the 70s expect a cooler mid-week with
highs in the mid 60s to mid 70s Tuesday and the mid 60s to lower
70s Wednesday.

Marine
Initially north winds will become southerly by Sunday. A cold
front will move through Monday night with winds increasing to
exercise caution behind the front in the Tuesday through Thursday
range.

Fire weather
Rh values will dip into the low-mid 20s on Saturday, but with
lighter winds red flag conditions are not forecast. Winds will
increase on Sunday and, with moderate mixing heights, this may
lead to increased dispersions Sunday afternoon.

Hydrology
Dry conditions are expected through much of the forecast period.

The exception is the Monday to Tuesday time period as a weak front
moves through. Precipitation with this will be limited to less
than a half inch and thus no flooding impacts are 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.
