    TUE MAY 23 2017
     
    WEATHER DISCUSSION:
     
    Continue warm today, as an upper ridge of high pressure dwells over the West Coast. By Wednesday a low tracks thru the PACNW, cooling things down a bit and allowing for the possibility of thunderstorms over the Crest. On Thursday and Friday, we will still be under the slight influence of low pressure, so dry weather and temps staying on the moderate side (but still warm). The weekend sees high pressure re-amplifying with temps on the raise again. As far as snow melt goes, the NWS Reno is now reporting estimate flow rates, for unregulated Eastern Sierra creeks and streams this week to be 2 – 2.5 times over current flow.

    Hot and dry conditions continue thru Tuesday, with a slight chance of convention over the Sierra, Wednesday into Friday.

Dry and a bit cooler for our area into Friday, with a chance of thunderstorms over the Sierra in Mono County. Right now the Memorial Weekend looks dry with temps trending back up again. -DMATT-

    THU MAY 18 2017
     
    WEATHER DISCUSSION:
     
    We had brisk winds yesterday, in the wake of a storm system currently over Utah. Much more tranquil weather will be in store for us in the upcoming days. Sunny skies, noticeably warmer temps, with lighter winds, all thanks to a building ridge of high pressure over the EPAC. A weak low pressure system will drop down into SOCAL by Sunday and this could bring the possibility of a few thunderstorms over the mountains thru mid next week. Other than that, the ridge will be the dominate feature for at least the next seven days. Wow, this hasn’t happened much to us this season. Only caveat is with higher temps, the current sluggish snow melt will increase flow in our streams and rivers. According the NWS in Reno, a prolonged warming trend could increase snow melt rates by 2 – 3X over the current flow. -DMATT

    WED MAY 17 2017
     
    WEATHER DISCUSSION:
     
    After showers and blustery cool temps yesterday, an upper ridge of high pressure will slowly build in overhead today. Even so, it will still be breezy and there will be a cool start to this mornings activities, with below normal temps. In fact tonight may be the coldest night of the week. By Thursday temps will begin to moderate upwards. Friday and over the weekend, sees that ridge continuing to build over the West Coast. So expect temperatures to continue their gradual warm up, say 5 degrees each day. -DMATT-

      By noon on Wednesday, SF bay area warming up nicely so the warming front may be headed your way.
