Synopsis

Note: No forecast was available earlier this week due to technical issues.

Well, high pressure aloft is dominant over most of the West today. Except for a minor trough passing well to our north on Saturday, the high pressure should be firmly planted over the state through next week. In short, expect mostly sunny days with well above normal temperatures. Some areas may experience record high temperatures for the date (particularly so next week, if today’s computer model consensus holds up).

There will probably be the usual issues of accurately predicting temperatures near the coast (campus included). The predicted, low level, off-shore flow shouldn’t get strong enough to suppress daily, ocean breezes. UCLA has a shot at reaching 90 degrees tomorrow, but “officially”, I kept the forecast a little lower. If the expected, marginal on-shore flow on Saturday turns out stronger than currently forecast, UCLA likely won’t surpass the upper 70s that day. Assuming high pressure aloft strengthens over the Southwest next week (peaking mid-week), temperatures next week (Tuesday-Thursday) should be higher than it gets today-tomorrow (UCLA may reach 90 degrees for a couple of days).

The longer range models do forecast a weakening and displacement of this dominant high pressure by the subsequent weekend. A general cooling trend should set in although a return to seasonable temperatures may not occur before the 23rd. In addition, a number of model solutions show a chance for some wet weather in the state (as early as 22nd in northern California; 23rd or later in the Southland). At present, none of the scenarios favor significant storms (wet weather may not even be widespread). There are, of course, some model solutions keeping southern California high and dry during the next two weeks (possibly remainder of the. month).

Next issued forecast/synopsis should be on Monday, 16 March.
