Posted by John . Filed under General |

Southern California may see its first “winter season” like storm torwards the end of this week, in September! Quoted from the National Weather Service “This could be the strongest mid latitude september storm for southern California in around 20 years”.

Here in the Coachella Valley we saw much cooler temperatures Monday with highs only in the low 90’s. Forecasted highs towards the end of the week are expected in the mid 80’s!!! Normal high for mid September is around 100 degrees.

STRONG SEPTEMBER STORM POSSIBLE LATE THURSDAY THROUGH EARLY SATURDAY…

A STRONG STORM FOR SEPTEMBER MAY MOVE THROUGH SOUTHERN CALIFORNIA LATE THURSDAY THROUGH EARLY SATURDAY. THIS STORM HAS THE POTENTIAL TO PRODUCE WEATHER VERY RARELY SEEN IN SOUTHERN CALIFORNIA IN SEPTEMBER. THIS COULD BE THE STRONGEST MID LATITUDE SEPTEMBER STORM FOR SOUTHERN CALIFORNIA IN AROUND 20 YEARS. SEPTEMBER STORMS WITH SOME SIMILARITY TO THIS STORM OCCURRED IN 1986 AND IN 1963.

THIS STORM IS CURRENTLY DEVELOPING OVER SOUTHWESTERN BRITISH COLUMBIA AND WILL MOVE QUICKLY SOUTHWARD ALONG THE WEST COAST TO NEAR THE BAY AREA BY WEDNESDAY EVENING…THEN WILL MOVE MORE SLOWLY SOUTHWARD ALONG THE CENTRAL CALIFORNIA COAST TO NEAR POINT CONCEPTION BY EARLY THURSDAY EVENING. MOVEMENT THEN WILL BE SLOWLY EASTWARD ACROSS SOUTHERN CALIFORNIA THURSDAY NIGHT THROUGH EARLY SATURDAY. THERE ARE STILL SOME DIFFERENCES IN THE TRACK FORECAST AND TIMING FOR THURSDAY THROUGH SATURDAY AND ESPECIALLY FOR THE POTENTIAL IMPACTS TO SOUTHERN CALIFORNIA.

STRONG WINDS WILL DEVELOP IN ADVANCE OF THIS STORM IN THE MOUNTAINS AND DESERTS FOR WEDNESDAY NIGHT AND THURSDAY. THIS STORM SHOULD BRING MUCH COOLER TEMPERATURES FOR THURSDAY AND FRIDAY WITH COOLEST TEMPERATURES FRIDAY. DEPENDING UPON THE EVENTUAL TRACK AND TIMING OF THIS STORM…THERE IS THE POTENTIAL FOR LOCALLY HEAVY PRECIPITATION AT TIMES FROM LATE THURSDAY THROUGH LATE FRIDAY. THIS STORM WILL BE QUITE COLD FOR SEPTEMBER WITH THE POSSIBILITY OF THUNDERSTORMS AND EVEN FOR SNOWFALL IN THE MOUNTAINS ABOVE 6000 FEET. THERE IS ALSO THE POSSIBILITY OF WATERSPOUTS OVER THE COASTAL WATERS AND TORNADOES OVER ADJACENT LAND AREAS.

STAY TUNED THE NEXT FEW DAYS FOR LATER UPDATES ON THIS DEVELOPING STORM.

    Not only did I hear about this on DW but on our local radios also. Could it be true that something may make it over the Mountain?

    That’s the question, will it have enough strength? I hope so. At the least it will hold these cooler temperatures around thru the weekend. Wow, its been nice the last few days!

    Excellent temps John. Snow in Sept? Maybe this could be the beginning to the end of our drought.
