.DISCUSSION...Today through Sunday



The building cloud cover and lingering humidity will help make this
afternoon be the coolest of the forecast with the upper 80s to mid
90s expected for most of the valley. The upper level pattern will
focus moisture farther to the east into the work week, leading to
drying conditions and allowing temperatures to increase as pressure
builds. As of the current forecast, temperatures look to peak on
Thursday with highs around 105 degrees for most of the valley, and
looking to exceed 110 degrees in favored warmer areas. Overnight
temperatures will also climb over the next few days, peaking in the
mid 80s to low 90s. These warming temperatures will increase
HeatRisk, with Major HeatRisk expected in the desert valleys for
Thursday. A pattern shift in the late week will offer a quick
cooling trend, bringing temperatures to near average over the
weekend.


This late week pattern change will also increase winds aross the
CWA. A trough builds to the north-northwest, and approaches the high
pressure to our east. This will lead to a stronger pressure gradient
and funnel winds between the two pressure systems, offering stronger
south to southwest winds across the CWA. Widespread winds above 20
mph with gusts above 30 mph will be possible Friday afternoon, with
the potential for infrequent gusts around 40 mph. Saturday and
Sunday`s afternoons call for slightly stronger winds and gusts than
Friday, with most areas seeing peak winds on Saturday and some
easing on Sunday. Longer-term models are in fair agreement over
these winds, and also that winds ease into the next work week.
