Short term (today through Friday)
Upper air analysis last evening showed a ridge over the middle of the
country and a trough along the west coast. At the surface, a cold
front stretched from central utah to the northern baja peninsula.

Closer to home, high pressure was centered over the gulf and winds
across our CWA were from the southeast. An upper level low will close
off as the west coast trough moves to the east. It will move across
the rockies today and tonight. This will push the surface front to
our western border by the evening and through our CWA overnight and
during the day Friday. Ahead of the front today the pressure gradient
will tighten and winds will be strong and gusty this afternoon
especially across the northern counties. Will issue a wind advisory
starting late morning and continuing through midnight. Winds could
gust up to 45 mph. As the cold front moves through our area it will
bring showers and thunderstorms starting across the north this
evening spreading across the rest of the area overnight and into
Friday. The best chances for convection will be during the day Friday
in the east. SPC still has a small part of our CWA in a slight risk
for severe thunderstorms and much of our eastern half in a marginal
risk. Forecast soundings show a low cape/high shear environment. This
suggests the most likely hazard will be damaging wind gusts.

Ingredients look better farther northeast outside of our cwa.

Long term (Friday night through Wednesday)
The front will move away from our area Friday night and there will
only be a slight chance for thunderstorms in the extreme east. The
weekend will be dry as high pressure moves in. Sunday night another
frontal system will move through texas, but a lack of moisture will
mean only a slight chance for precipitation and only over the
northeast. Another frontal system will move into the region bringing
a chance for showers and thunderstorms Tuesday and Wednesday.

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.
