Short term (today through Tuesday)
We will begin the day with a low overcast ceiling as boundary layer
cooling and a strong inversion has led to extensive stratus and fog
this morning. This should lift and scatter through the morning, but
high to midlevel clouds will start to increase in the afternoon. We
will also have a strengthening southerly LLJ late in the day, which
may create some downslope warming drying in the lee of the
mountains.

Showers are expected to enter the plateau counties late in the
afternoon. Convection to our west is expected to be weakening as it
approaches due to weakening frontogenetic forcing and a lack of
instability. The models depict a pre-frontal convective line moving
across al ga that will cut off the northward advection of higher
theta-e air into our area. As a result, the forecast will delay the
onset of categorical pops in the valley until midnight when forcing
along the cold front starts to enter the area. The model trend has
been toward less instabilty, which was already low with previous
runs, so a severe threat is unlikely. Will maintain a mention of
slight chance of thunderstorms, and a mention of gusty winds
possible in the hwo. The cold front will exit Tuesday morning with
advection of drier and cooler air following in the afternoon.

Long term (Tuesday night through Sunday)
Quiet pattern Tuesday night through Thursday night as high pressure
builds over the forecast area. Zonal flow and cooler temperatures
will cause lows to drop again into the upper 30s to lower 40s both
Wednesday and Thursday mornings. More frost possible both days but
no widespread freeze yet. Temperatures only in the 60s Wednesday but
warming to the lower 70s Thursday.

Next change in the pattern begins Thursday night into the weekend
with the canadian and ECMWF showing a closed low develop over the
southwest states and northern mexico with a surface low and front
moving out of the plains by Saturday with rain spreading over the
area through the weekend. GFS model shows next system as an open
wave that forms with a central plains trough Thursday night and then
spreading precipitation into the area early Friday and moving out by
early Saturday with high pressure overhead for the weekend. Will use
a blend and have rain move in Friday with front but linger through
the weekend as secondary low pressure system moves up from the
southwest Saturday and moves through Sunday. Colder temperatures
Friday and Saturday but warming Sunday as system shifts east and
slight ridging aloft develops.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
