..DISCUSSION FROM RNOFWFVEF
CHANCES FOR SHOWERS AND THUNDERSTORMS LOOK TO BUILD ACROSS MOHAVE
AND EASTERN LINCOLN COUNTIES THIS AFTERNOON AND LAST THROUGH THE
NIGHT. SLIGHT CHANCES WILL ALSO BE POSSIBLE FOR PORTIONS OF SAN
BERNARDINO, CLARK, AND NYE COUNTIES, BUT LOOK FEW AND FAR BETWEEN.
STORMS THAT FORM OVER MOHAVE AND EASTERN LINCOLN COUNTIES WILL
PROVIDE GOOD CHANCES FOR WETTING RAIN AND LIGHTNING WITH THE
POTENTIAL FOR LOCALLY GUSTY WINDS AND FLOODING FROM TRAINING STORMS.
RAIN CHANCES DISSIPATE INTO THE LATE MORNING ON THURSDAY WIT BREEZY
WINDS EXPECTED THAT AFTERNOON. OUTSIDE OF SOME SLIGHT CHANCES FOR
RAIN ON HIGHER TERRAIN, THE REST OF THE FORECAST PERIOD LOOKS DRY
WITH BREEZY AFTERNOONS THROUGH THE WEEKEND BEFORE WINDS EASE IN THE
NEXT WORK WEEK. THE PATTENS CHANGE OVER THE WEEKEND WILL LEAD TO
REDUCED HUMIDITIES WITH DAYTIME RHS FALLING BELOW 10% FOR MOST OF
THE DISTRICT AND OVERNIGHT RECOVERIES FALLING BELOW 25%.
..DISCUSSION FROM LAXFWFSGX
THE MARINE LAYER IS EXPECTED TO BE AROUND 3500 FT DEEP THURSDAY
MORNING, WITH HIGH TEMPERATURES 5 TO 10 DEGREES BELOW AVERAGE FOR
THE MOUNTAINS AND INLAND VALLEYS. WARMING CONDITIONS EXPECTED OVER
THE WEEKEND WITH A SHALLOWER MARINE LAYER. IT WILL DRIER FOR THE
DESERTS FRIDAY THROUGH THE WEEKEND WITH LOWEST RELATIVE HUMIDITY
FALLING TO 10 TO 15 PERCENT EACH AFTERNOON, BUT WITH MUCH WEAKER
SOUTHWEST TO WEST WINDS DURING THE AFTERNOON AND EVENING, MOSTLY
GUSTING TO 15 TO 25 MPH FOR SATURDAY AND SUNDAY.
..DISCUSSION FROM PHXFWFPSR
PERIODS OF SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO CONTINUE TODAY, FOCUSING MOSTLY ACROSS THE EASTERN
DISTRICTS THIS AFTERNOON THROUGH THIS EVENING, HOWEVER WIDESPREAD
ACTIVITY OVER MUCH OF THE LOWER DESERTS CAN BE EXPECTED. THERE WILL
BE A HEAVY RAINFALL AND FLOOD THREAT WITH THE ACTIVITY. MOISTURE
LEVELS WILL BE ELEVATED MOST AREAS, HIGHEST ACROSS EASTERN
DISTRICTS, WHERE MINIMUM RH THIS AFTERNOON WILL BE AROUND 50-60%.
MINIMUM RHS WILL BE LOWEST ACROSS SOUTHEAST CA, WITH VALUES AROUND
20-30%. A DRYING TREND WILL BEGIN THURSDAY WITH CONDITIONS BECOMING
VERY DRY BY THIS WEEKEND. MINIMUM RHS BY SATURDAY DIP TO 10-25%
ACROSS THE LOWER DESERTS (LOWEST ACROSS WESTERN DISTRICTS).
OVERNIGHT RECOVERIES WILL STILL BE GOOD ACROSS EASTERN DISTRICTS
THIS WEEKEND AT 40-60%, WHILE WESTERN DISTRICTS HOVER AROUND 25-45%.
THE DRIER AIR MOVING IN WILL ELIMINATE RAIN CHANCES BY FRIDAY, WITH
LOW CHANCES IN GILA COUNTY THURSDAY AFTERNOON. WINDS WILL FAVOR THE
SOUTH TO SOUTHEAST OVER MUCH OF THE AREA THROUGH WEDNESDAY WITH
GUSTS OF 20-30 MPH AT TIMES ACROSS SOUTHWEST AZ AND SOUTHEAST CA. IN
THE FOLLOWING DAYS WINDS WILL RETURN TO A MORE TYPICAL DIURNAL WITH
MODEST AFTERNOON UPSLOPE GUSTINESS.
