(tdy-Mon), 25/920 AM.
***UPDATE***
Lots of mid and high clouds today as a very weak upper level system moves over the area. Could get a stray drop or two this morning or early afternoon but the best chance for any sort of light measurable rain would be at least late afternoon but more likely this evening. Amounts are expected to be under a tenth of an inch, with some areas, especially in the rain shadow of the Transverse range, getting no measurable rain. In any case, a very low impact event.
***From Previous Discussion***
Gusty SW winds will affect the mtns and the interior later this afternoon. It will be cloudy day as a combination of low mid and high clouds moves over the forecast area. 5 to 10 degrees of cooling will bring max temps across the csts/vlys down into the 60s.
Fairly strong SW to W winds will continue across the Antelope Vly and its foothills this evening. There is a about a 40 percent chc of the gusts reaching advisory levels of 45 mph. The chc of rain will diminish to only a slight chc as the evening turns to night and the storm moves further to the east.
There will be minimal threat of some morning showers on Sunday just in cast the system moves out a little slower than expected. Otherwise, the day will be dry with decreasing clouds. Most areas will see 1 to 2 degrees of warming but the the Antelope Vly and nrn mtns will cool a bit as a cold pool of air will linger.
Weak troffing will cover the state on Monday and hgts will be a below normal 564 dam. Skies will start out partly cloudy, but will turn mostly sunny by early afternoon. The extra sunshine will bring about 2 to 4 degrees of warming. Despite this warming max temps will end up 4 to 8 locally 10 degrees blo normal with max temps only in the mid 60s to lower 70s across the csts/vlys.
(Tue-Fri), 25/243 AM.
Benign weather on tap for Monday as the weekend storm pulls further to the east and a weak ridge moves in from the west. Skies will be, at worst, partly cloudy. 2 to 4 degrees of warming will bring cst/vly max temps into the upper 60s and lower 70s.
Still not the best mdl agreement but there is definite improvement. The trend to lesser chances of rain continues as well as pushing the timing back. Now Wednesday looks dry with only a bare minimum chc of light rain Wednesday night and/or Thursday morning. And even if it does rain, rainfall amounts will be insignificant Skies will be partly cloudy for the most part with a chc for mostly cloudy conds with the rain chances. Look for clearing skies and warming Friday as a ridge builds into the state.
Max temps will rise Tue, Wed and Fri with only minimal cooling on Thursday. Friday's max temps will be 3 to 6 degrees above normal with vly highs reaching into the lower to mid 80s.
