SYNOP:
***Isolated wet thunderstorms over the mountains and deserts through this weekend and then increasing next week***
There will be a substantial decrease in shower and thunderstorm activity across the region today as the center of high pressure over the Great Basin moves westward to Central California. However, isolated wet afternoon showers and thunderstorms will form over the Sierra and over the mountains and higher desert locations of Southern California east of the Cajon Pass through this weekend. Thunderstorm activity will increase over the mountains and deserts Monday through the end of next week as the center of the high moves eastward over the Great Basin. A weak disturbance in the flow around the high pressure area, may bring shower and thunderstorm activity to the coastal and valley locations of Southern California toward the middle of next week. Temperatures will be near to a little above normal through the end of next week, with 80s to low 90s across the mountains and 90s to 102 in the valleys. Minimum humidity will be mainly between 20% and 40% through the end of next week. However, across Central California west of the Sierra, minimum humidity will be mainly in the teens starting Sunday. Winds will be light through the end of next week, except there will be strong and erratic winds in and near any thunderstorm.

FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA

Inland Empire LOW NONE
San Bernardino County Mountains MODERATE MODERATE
High Desert Including Apple and Lucerne Valleys LOW LOW
San Gorgonio Pass Near Banning LOW LOW

Flash Flood Codes: GREEN: NONE YELLOW: LOW ORANGE: MODERATE RED: HIGH

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
A very moist airmass will remain in place today with scattered showers and storms expected this afternoon. Storms that develop today will continue to carry the threat of localized flash flooding, lightning, and erratic wind gusts. A slow downward trend in rain chances is expected this weekend as high pressure builds over the region and slightly drier air works in from the west. Temps will rise back up near seasonal normals through the weekend.

Southern NV, Northwest AZ, Southeast CA

TODAY/TONIGHT
Primary threats today: heavy rain & flash flooding
Storms should begin later than yesterday 10 AM-Noon.
Storms will move at 0-5 MPH
Rain rates 1-2″/hr.

Decrease in coverage of storms, particularly across the lower Mojave Desert areas.
Best chances for storms will remain across Mohave County, southern Great Basin, and northern Inyo County; especially across the higher terrain in these areas.

SAT & Beyond
Moisture remains in place
Storm chances gradually diminish through SUN, then may increase early next week (especially SE of I-15)
Temperatures rising to near or slightly above normal by next week

SPECIAL NOTES: none at this time

DAILY FUELS/FIRE POTENTIAL:
The potential for large fire will be relatively low across the region through Saturday as thunderstorm activity decreases and becomes focused over the higher terrain and humidity remains fairly high. The large fire threat will increase a little across the lower elevations of Central California Sunday through the end of next week as humidity becomes very low over this part of the region and gets combined with very warm temperatures. Dead fuel moisture has increased over the past few days due to significant rainfall in the mountains and higher humidity in the valleys. Expect light initial attack activity across the region through weekend and then moderate IA activity next week as thunderstorm activity increases.
