Discussion
Today and tonight:
continued cooler than normal and dry. The 00z Tue jan sounding
had a pwat of 0.30in and dew points were running in the mid to
upper 40s. This cool dry airmass over our CWA will change very
little through tonight. Early morning surface analysis had a
1027mb high centered over the ohio river valley that will shift
east to the mid atlantic seaboard by sunrise Wednesday. This will
maintain a light northeast to east wind across our region and
limit moisture return. Under a light wind and full insolation
today, temperatures will top out several degrees warmer than
yesterday but still a couple degrees cooler than normal. Most
sites will reach the mid 70s. Under clear skies and a near calm
wind tonight, strong radiational cooling of our dry airmass will
lead to morning lows cooler than normal again. Lows will range
from the lower 40s east to the upper 40s south and west. Normal
lows run in the lower 50s. 22
Wednesday through Monday:
there is still some uncertainty regarding the forecast for next
weekend, but overall confidence is increasing through the extended
portion of the forecast. Continued quiet and generally warm
weather through the middle to end of this week will be driven a
building shortwave ridge over the gulf coast region. But then our
attention quickly turns to an upper-level shortwave trough moving
onshore the west coast on Friday and over the central CONUS over
the weekend. The latest round of operational guidance has finally
come into pretty decent agreement regarding the timing and depth
of the trough and related surface features.

A sharp north-south oriented cold front is expected to work its
way through the arklamiss region sometime between late Saturday
night and Sunday night, driven by a strong northern stream jet.

Return southerly flow ahead of the cold front's arrival will bring
a northward surge of moisture, and pwat values could be near 1.75
inches along and ahead of the front. Therefore expect
thunderstorms with possibly heavy rainfall as the front sweeps
through the region. Currently do not expect significantly colder
air behind the front as bulk of the cooler air looks to remain
north of our region, and in fact shortwave ridging resumes in the
immediate wake of the front. Indications are for a deeper trough
to develop over the upper midwest early next week and push a
reinforcing cold front into our forecast area just beyond the
7-day forecast. Nf

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.
