KEY MESSAGES
- Upper ridging will keep above average temperatures in place through the weekend. Heat related effects are possible especially Saturday when the humidity is a factor.
- There is a low chance of thunderstorms through Sunday but timing amounts and placements are low confidence.
- A brief cooldown is expected Monday.
DISCUSSION
WEATHER PATTERN OVERVIEW:
Upper ridge over the western state will be knocked down slightly by a shortwave/upper low pushing through western Canada through the weekend. This wave will tap the deep monsoonal moisture to offer daily chances for thunderstorms. High precipitable water values will mean any given storm could be a prolific rainfall producer. In addition, the SPC has included the northwestern corner for today, and the southeast corner for Sunday in a marginal risk for severe thunderstorms but the latest CAMS are showing low chances for our CWA.
The hot temperatures will be shifting eastward through the weekend, with temperatures dropping close to normal by Monday as the shortwave moves east.
The upper ridge returns next week and that will allow temps to rebound to well above normal by the end of the week.
FORECAST CONFIDENCE & DEVIATIONS:
No significant deviations were made to the forecast. Confidence for thunderstorms is generally low for much of the cwa through Sunday.
AVIATION
VFR. Isolated to scattered thunderstorms pushing in from the west may lead to brief reductions in ceilings.
GGW WATCHES/WARNINGS/ADVISORIES
None.
