Sct-bkn low endVFR gradually lowers to MVFR CIGS mid to late evening
as s-se winds decouple only slightly to 12 to 16 kts. Brief lowering
to ifr is possible, however, strong low level jet with some mixing
will allow MVFR to prevail overnight into morning. Mixing on Thursday
raises CIGS to low endVFR with sct-bkn in the afternoon as winds
increase to 15 to 20 kts with gusts as high as 30 kts. MVFR cigs
return Thursday evening.

short term (tonight through Thursday night)...

late spring doldrums are underway as a broad upper high continues to
build over the southeastern us. Afternoon and evening southerlies
will remain brisk through late this evening with a shortwave
disturbance lifting across NW tx into ok enhancing the sfc pressure
gradient over north and central tx. Min temps are thus expected to
remain warm with dewpoints staying up as well. At least one model
guidance is depicting near record high min temps for sat, but will
only shift slightly warmer than the blended guidance. MAX temps are
adjusted slightly up to account for some bias corrected numbers that
may still be influencing guidance blend starting points from the
previous week. Only remote areas to the west are considered close
enough to the instabilities in the SW flow over the mexican plateau
are considered for a slight chance of deeper convection, but there
could be a brief intrusion of sub-cap showers over southeast counties
from coastal activity moving inland Thursday afternoon.

Long term (Friday through Wednesday)...

the broad subtropical ridge remains nearly stationary over the
weekend through Monday. On Tuesday, heights over NRN mexico fall and
shift into W tx as a large and deep upper low is forecast to develop
over the NRN plains.

Friday through Monday should see mostly persistence weather, with
perhaps more insolation and warming potential to widen diurnal
temperature trends each day. Later forecast updates could see these
daytime warming trends accelerate should the morning cloudiness
periods vacate the area faster. Then on Tuesday, an expected increase
in westerlies from the deepening storm system to the north should
enhance onshore winds and possibly tap into a potentially unstable
eastern pacific. The 12z GFS and ecm cmc deterministic runs are at
odds on which is the case, so will favor persistence on rain chances
which would remain very low, but give a nod toward the blended
guidances which slow the warming trend and assume slightly more
cloud cover for Tuesday into Wednesday.

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.
