SEa fog may develop tonight across the bays and near shore waters where water temperatures are cooler. A frontal boundary will move across the waters Monday night and trigger isolated showers and Thunderstorms. A weak to moderate northeast flow will develop behind the front Monday night. A moderate northeast flow is expected Tuesday after the frontal passage. Weak to moderate onshore flow will develop Wednesday and continue through Friday as surface high pressure moves east and as surface low pressure deepens over the southern plains.

Short term (today through Tuesday)
Upper level low moves from the midwest to the mid-atlantic coast
today pushing a cold front into central texas during the
afternoon. The front will push through south texas overnight.

Timing remains pretty consistent between models, pushing through
victoria before midnight and reaching the southern edge of the
forecast area by around sunrise or shortly after. While moisture
is rather limited... Pwat increasing to around 1.25", isolated
convection will be possible. GFS model soundings show fairly good
cape developing around victoria crossroads region this
afternoon evening with a weak cap. Thus isolated thunderstorms
would be possible if temperatures warm sufficiently. Farther
south, warmer mid-level temps will be in place but elevated
convection would be possible as the front pushes through. Will
keep slight chance pops over much of the area for the overnight
period. Added a slight chance showers southwest for Tuesday
morning as front may not be quite through there by 12z. High
temperatures today expected similar to yesterdays values, mainly
in the 80s. Could touch 90 degrees west. Lows overnight should be
cooler as drier air filters in behind the front. Temperatures
Tuesday will be cooler Tuesday in the post frontal airmass, mainly
in the mid and upper 70s.

Long term (Tuesday night through Sunday)
Tuesday night through Thursday, the deterministic gfs ECMWF predict
an upper ridge with n-s axis to move slowly ewd across the cntrl
conus cwa, while an upper disturbance enters the west coast. Gfs
deterministic predicts near normal pwat values over the CWA near the
beginning of the period, increase to slightly above normal by
Thursday. Do not anticipate significant precipitation during this
period given the upper ridge. Friday, both the GFS and ECMWF predict
the upper disturbance to move ewd across the rockies and approach
the plains. Associated limited synoptic scale lift is expected
across the CWA and combine with moisture to generate elevated
isolated convection. Friday night Saturday, the gfs ECMWF predict a
cold front, associated with the upper disturbance, to approach enter
the CWA and increase the chance for convection. Drier and cooler
conditions expected Saturday night Sunday.

Marine
Patchy sea fog will be possible today and tonight before a cold
front moves through the area. Light onshore flow can be expected
ahead of the front with a moderate to strong north to
northeasterly flow behind the front on Tuesday. Expected scec
conditions, but at this point looks to stay below SCA criteria. An
upper level disturbance will contribute to isolated convection
Friday. The combination of an upper disturbance and associated
cold front will result in scattered convection Saturday Saturday
night. Drier and at least scec conditions expected Sunday after
frontal passage.

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.
