Synopsis
It looks like high pressure aloft will keep California in a mostly dry state this week and probably next week as well. There will be a weakening storm that passes through the northern third of the state on Wednesday, but significant precipitation isn’t anticipated up there. Other than varying amounts of high clouds Wednesday, dry weather will prevail in southern California (separate, weak, upper level trough was responsible for high clouds earlier today).
It wound up warmer today at UCLA (74 degrees) than I expected. It can be a little tricky with when ocean breezes could offset (partially) the warming effects of an off-shore flow pattern (applicable mainly to areas nearer the coast). My preliminary, morning forecast might be a little on the cool side (as was the case for the today period). However, today’s extra warmth may be a fluke. So, I left the forecast numbers unchanged. More uncertain for me it the period late this week. High pressure aloft is forecast to get stronger than it was today. So, there is some chance that the campus area, along with the more inland, coastal plain, could warm into the low/mid-80s (Friday into the weekend).
The various, computer model forecasts show ups and down in off-shore flow strength through next week. Much warmer than normal weather appears likely, but just how warm it actually gets, remains to be seen (probably not higher than mid-80d for warmest locales). There appears little chance for a shallow marine layer to develop for most or all of next week (i.e. get use to low relative humidity for a while).
There are some longer range model forecasts of wet weather in the Southland sometime after the 7th of February. However, there has been a trend of delaying this event as time goes on (at one time, wet weather was predicted for 29 January…now forecasting sunny, warm weather). Even if wet weather occurs as some model solutions show, they favor at most, a modest strength storm (quarter to half inch rains in the lowlands away from the mountains).
Next issued forecast/synopsis should be on Monday, 2 February.
