This is about to change as a weak upper low has developed west of the Bay Area this evening. This feature will move further south with time putting the high country of Mono County under at least weak upper divergence. Our air mass continues very dry and so expect mainly dry high based thunderstorms with strong outflow winds next to the rain shafts. The National weather service has issued a fire weather watch Wednesday afternoon and Thursday afternoon, as lightning over a very dry forest will likely create hazardous conditions with strong gusty outflow winds. Most Storms will be over Northern Mono County Wednesday but develop further south over Southern Mono County Thursday. High temperatures moved into the low 80s Today. The bump up from the upper 70s was probably due to a weakened zephyr. Little change in temps are expected with highs in the low 80s. The upper divergence that is currently developing will weaken this weekend. Thus thunderstorms will become more isolated. Note this is not the Summertime Monsoon!! (Seasonal wind) Outlook for next week: Its been long in coming but the Summertime Monsoon looks to arrive during the second half of next week. Latest guidance shows the subtropical high developing over Texas this weekend then expanding westward next week. The GFS model shows PWAT (low and mid level moisture) really increasing over Southern CA by middle of next week with hot humid weather becoming more likely during the 2nd half over So Cal.. A northerly surge is expected over most of the State by the following weekend. Although it is too soon to tell what type of focusing will highlight the pattern; it looks like we will get into a wet thunderstorms pattern during the last week of July. This pattern change next week completes the transition to our Sierra Summertime Thunderstorm pattern. Beautiful sierra weather is in store for the high country the next 7 to 10 days…..After Mid Month, the heat builds along with thunderstorms possibilities… Thursday July 2, 2020 Posted at 12:21 pm by Howard Dry Comfortable weather with breezy afternoons are expected through the 12th of July with Summer heat and the arrival of the Summer Monsoon not expected until after the 15th of July. Weather Summery: A Trof of low pressure aloft over the Pacific Northwest will remain stationary for the next 8 to 14 days. This will give the Mammoth area below normal temps week 1 (70F-75F), then more seasonal temps week 2. (75 to 77). Overnight lows are expected in the 40s and 50s. Additionally, this Trof will enhance our afternoon and evening Zephyr. Thus, late afternoon and evening breezes will be stronger with gusts to 35 MPH. Our air mass will remain dry with virtually no thunderstorms while this pattern continues with a strong zephyr. Longer Range: Latest European Guidance suggests that this Upper Trof will retrograde just after Mid-Month to the Gulf of Alaska. (15th-18th) This allows heights to build over the desert southwest along with the heat. The EC model had 500MB heights by the end of the 15 day period, near 600DM. This would complete the transition to Summer, and the harbinger of the AZ monsoon?…. Well see. (depends upon the config of the Subtropical ridge.) Over the far west, the heat will build during the 2nd half of July. Summertime afternoon and evening thunderstorms may become more likely. Big question this morning is……After the upper Trof retrogrades west…will it redevelop over the pacific NW again shortly after? Dr Howard and the Dweebs………………………….:-) Last week of Spring begins with breezy conditions Monday through Tuesday and ends on a calm note with above normal temperatures next weekend as Smooth Spring hand-off expected to Summer…… Monday June 15, 2020 Posted at 8:50 am by Howard Fathers Day: It’s the first full day of Summer and it feels like it. Temps today should hit 80 degrees in Mammoth. At 12:00PM a light zephyr had begun. For those that have never experienced Mammoth in the Summer, I can say without reservation, that Summers in Mammoth are nothing short of heaven on earth! For the most part, Summers are dry, with low humidly. Days are sunny with the exception of a handful of thunderstorm days. The weather outlook this upcoming week will be fair with high temperatures some 10 degree above normal. As pressures build aloft this weekend, there will still be an afternoon Zephyr, A subtropical high will build aloft over the state for lighter afternoon breezes Monday and Tuesday. Afternoon convection will drive mainly isolated late afternoon thunderstorms Mid Week. In the longest range, an early Summer Trof will bring some 10 to 15 degrees of cooling the end of the month into the first few days of July. This Trof looks to bring gusty winds fire weather concerns. Nighttime lows may back down into the 30s for a day or two. However, highs will still reach upper 60s and low 70s. All the global models have this Trof for the 29th, 30th and first few days of July. _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The westerlies continue to their recession to the north this week as Spring shifts to Summer this weekend. These are the very longest days of the year…… Sunset averages about 5:39 PM with Sunrises at 5:30 AM. Saturday’s daylight is 15 hours and 18 minutes. The Summer Solstice occurs at 2:44 PM Saturday Local time. 500MB charts and progs show a slow migratory short wave over the Pacific NW Monday and Tuesday with 130 knot upper Jet NW/SE through far Northern CA. Expect breezy weather today through Tuesday. Wind advisories are hoisted for Mono County Lakes, 3:00PM Monday through 10:00PM Monday night. However, because the weather system is so far north, little if any cooling is expected the next few days…. Last weekends storm look to be the last of the season as the westerlies continue their retreat to the north…. Cut off lows may still enhance afternoon convection, the next few weeks for afternoon thunderstorms, however, afternoon temps likely to stay warm!! 70s….
