Wind shift happened last night….. So we are out of the smoke until the upper flow comes out of the north again or the fire is out….
Expect breezier days and eventually night ahead….
It was quite the smoky morning Sunday with Air Quality in the tank until the inversion and southwest breeze broke it up by 10:00AM…..
It may be smoky again tonight into the early AM hours before additional breeze follows later Monday AM.
A similar pattern develops this new week as what we had a week ago as a small upper low off the Coast of Northern BAJA lifts north and moves in over Southern CA this next week. This time the upper forcing with its small features move over Southern CA and so Mammoth will not get the showers we got last Sunday in a similar scenario. Southern CA will get the forcing and moisture and showers and humidity are expected to increase Monday and into Tuesday. Like last week, another system from the Gulf of AK will be the kicker. That system will bring strong SW flow Wednesday into Thursday and bring a good 20 degrees of cooling by Thursday. Although there may be some showers Thursday AM with the FROPA and a dusting of snow above 8000 to 9000 feet, the system is moisture starved as the bulk of the moisture this time is well east and south of our area. Expect strong winds over the upper elevations Wednesday afternoon and especially Wednesday night. WSW Winds are forecasted at about 35 to knots at 700MB Wednesday evening and so sierra crest winds my gust to 80 to 90 mph. Winds will back from the NW by Thursday night. Friday AM looks the coldest with lows in the 20s and low 30s. What a rude intro to the first day of Fall! 😉
Longer Range builds a ridge back in that following weekend for a FAB weekend.
