Good Morning.
..Today we begin a warming trend that will last through most of the week ahead. High pressure will slowly build across the West over the next few days. Temperatures for the mountains will warm into the mid to upper 80s with some of the warmer places reaching into the low 90s by Thursday.
..LOOKING AHEAD:
..After the area of High pressure peaks over our area on Thursday, it will move to a position over the 4-Corners States at 597dm. The winds around the center of the High will bring mid and upper level moisture back into the Region starting Friday. Thunderstorms will be likely beginning on Friday lasting on and off through early next week.
..These possible T-Storms will be most likely over the Desert areas including the Colorado River and up into the Big Bear area.
..At the same time a Trough of Low pressure will move onshore across the PAC-NW. This will help to bring some cooling to the SoCal Mountains beginning on Friday lasting into the following week.
..CRYSTAL BALL OUTLOOK:
..Here is where things get interesting.
..Looking out towards the end of the month, the long range models are favoring multiple Tropical Storms developing in the Eastern Pacific then traveling Northwesterly offshore of the Coast of Mexico and Baja Ca. As it looks now, we could see wetting rains for SoCal around the 27th and 28th of August from one of these weaking Tropical Storms. Beyond that time, there are expected to be several more Tropical disturbances develop in the general area that may affect SoCal. The SST’s are very warm (as much as 10* above normal) off of San Diego and along most of the SoCal coastline. The development of storms and or Hurricanes to our South will be something to watch for in the coming weeks. RC*
