Short Term
High pressure currently building over the area with some light freezing temps during the overnight mainly for northshore areas over teh weekend. This will be the rule for the next few days with a slow warming trend into the end of the weekend.

.LONG TERM (Monday through Thursday)... A strong cut-off low and mid/upper level trough are expected to develop and move near the Desert Southwest/Baja/northwest Mexico region Tuesday into Wednesday, however the models develop significant differences the position, strength and timing of the main system and shortwave troughs and impulses that eject out into the Plains during the middle to latter pater of the week along with the associated surface cold front. At this point, the ensemble solutions favor using the NBM guidance Probability of Precipitation which are in the slight chance to chance range Tuesday night through Thursday and holding a cold front back from the area until Thursday night or Friday morning.

Marine
Small craft advisories will remain into this afternoon as strong winds will continue over mainly open gulf waters. Strongeset wind speeds will be in the 20-30kt range with some gusts to gale force mainly in offshore waters. Seas will also remain around 6 to 10 feet in the offshore waters. The wind field should quickly relax with winds of less than 10 knots by tonight as high pressure settles directly over the waters. Seas will also fall back to around 2 to 4 feet in response to the lighter winds. Another front will push through on Sunday, and this will allow winds to increase to 10 to 15 knots for Sunday night and Monday. Return flow will begin to develop Monday night into Tuesday but should remain around 10kt.
