Discussion
Today and tonight: warmer than normal temperatures will continue
through tonight. Dry weather is expected to continue today but rain
chances look to return tonight across the north. Early morning water
vapor imagery rap analysis showed the circulation around a 592dam
ridge extending west across the gulf coast states from the western
atlantic. Early morning surface analysis had 1029mb high centered
over the mid atlantic seaboard ridging back to the west across the
tennessee valley. This ridging surface and aloft will try to remain
dominant over our region today as they weaken and allow a northern
stream shortwave to help drop a cold front toward our CWA by
evening. The 00z Friday jan sounding had a pwat of 1.38in. Moisture
will be slow to increase today but models agree that pwats will
surge above an inch and three quarters tonight ahead of the
approaching cold front and support light rain development. The cold
front is expected to move into our northwest most zones after
midnight and push just south of the interstate 20 corridor by
sunrise Saturday. Most of the measurable rainfall looks to be
anafrontal and total between one tenth and a quarter of an inch
across the northern third of our CWA tonight. Although not record
temperatures, highs this afternoon will top out in the low to mid
80s across the southeast half of the CWA while mid to upper 70s are
expected across the northwest. Tonight cloud cover and increasing
rain chances will hold temperatures in the low to mid 60s along and
ahead of the cold front. Temperatures will drop into the 50s behind
the cold front. 22
Saturday: by Saturday morning, a cold front will bisect the area,
though the influx of drier air will lag slightly behind it, first
arriving later in the afternoon in the north and in the evening
across the south. Temperatures will be held down, however, around 10
degrees cooler than today in many areas. In spite of respectable
upper forcing, the moisture surge along the front will be modest at
best, so we're anticipating a broken band of showers to accompany
the front. This will push southward across the area through the day,
with rain ending for most areas north of i-20 by midday and for the
remainder of the area before sunset. Clouds won't hang around for
long, with clearing occurring in most areas by the early evening.

Saturday night through Monday: low level cold advection will
predominate through Sunday, as a surface high shifts from the upper
plains through the mid ms valley. This will keep highs in the 60s in
most areas Sunday, with lows in the 40s Saturday and Sunday nights.

A few of the typically colder areas may dip into the 30s Monday
morning as the surface ridge makes its closest pass; however, the
potential for clouds under an upper jet streak precludes greater
confidence in a bolder low temp forecast at this juncture.

Conditions will slightly moderate Monday as the high shifts east
toward the atlantic coast.

Tuesday through Thursday: models continue to suggest the active
southern stream of the upper jet will spur on development of another
storm system during the mid to late week time frame. However, run to
run and model to model consistency remain poor. Latest guidance is
more suppressed with the coastal surface low as an additional strong
surface high builds over the midwest during the middle of the week.

Still, there appears to be a decent chance for at least showers by
Wednesday into Thursday. Only minor changes were made to the
inherited forecast during this time frame. Temperatures are expected
to be more seasonable, though perhaps still slightly below normal.

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.
