Short term (today through Thursday)
As of 3 am, radar loops showing the southern portion of the squall
line to be losing its near severe and mostly elevated velocity
signatures, but will leave up the watch along the front edge over
i-35 for another hour. Following the trends of the hrrr/rap, will
show a more progressive clearing trend for the morning pops and plan
on using conservative hwo wording regarding the late morning strong
storm potential over southeast counties.

Continuing the trend on temperatures, earlier clearing should
translate to warmer than blended guidance MAX temps for today. Good
midday packing of isobars over the edwards plateau should enhance
mixing and drop rh values in the low teens along the rio grande,
while picking surface winds to around 20 mph with gust over 35 mph nw
of drt. Radar precip estimates suggest all of val verde county had
receive over 0.2 inches of rain with the drier 10-hour fuel moisture
areas around drt having a little more. Thus will expect this moisture
to offset the critical fire weather conditions forecast for western
val verde county and settle on a near critical wording. Farther east
and south, winds and especially gusts should drop off to lower
values. NW boundary layer to 850 mb winds at 20 to 35 mph should
enhance cooling and drying across the region, leaving a seasonal
morning low in the upper 40s north to mid 50s southeast. Westerly
transport winds resuming for Wednesday will be much lighter but
should still bring afternoon temps back to above normals.

Long term (Thursday night through Tuesday)
Light winds should continue Thursday night, and there may enough
ground moisture for some patchy ground fog given the rains. Will keep
with the model data and leave out for now. Returning south winds
Friday will accelerate late in the day as another large upper low
drops southeast across the great basin towards tx. Initially, the
mid levels of the atmosphere will be very dry, so there should still
be abundant sunshine and warm temps for Friday. Continued deepening
of the low level moist layer and closer approach of the upper low
will likely bring a mostly cloudy and not as warm day Saturday, with
a dryline feature suggested to set up over central tx in the afternoon
by deterministic models. As suggested in the SPC extended outlooks,
instability and wind shear would likely be sufficient for a few
severe storms. Continued sewd digging of the upper low is then
expected to bring additional rounds of storms from the SW Saturday
night with rain still likely over the eastern two-thirds of the area
Sunday. The repeated rounds of rain could mean some locally heavy
downpours over 2 inches will be possible this weekend. Gfs/ecm
solutions show good agreement on the northeastward ejection of the
upper low Sunday evening with mostly stable and warm weather to
follow for early next week.

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.
