SYNOPSIS
Unseasonably warm temperatures with mostly sunny skies will persist through the first half of the week with the warmest days yielding widespread minor heat-related health risks. The first in a series of weather systems will move through the region Wednesday and Thursday resulting in a temperatures retreating closer to the seasonal normal while also supporting occasional periods of strong, gusty winds.

DISCUSSION
Dry westerly flow under the influence of low amplitude ridging remains situated over the SW Conus early this afternoon providing a synoptic setup yielding much above normal temperatures. With H5 heights hovering near 580dm over the next 60 hours, temperatures 8F- 12F above normal should be common with tomorrow being the warmest day. Very gradually through the middle of the week, anomalous troughing over the East Pacific will edge towards the west coast with modest height falls entering the western CWA as early as Tuesday resulting in the first signs of a cooling trend. In addition, the incoming system will force an increasingly tightened pressure gradient and progressively prevalent afternoon gustiness into the middle of the week.

Ensemble guidance is somewhat more consistent showing an initial shortwave and compact vorticity center nearing the southern California coast Wednesday with the bulk of the cold core lifting through western and northern Arizona Thursday. As anticipated, the timing of system is slightly slower than previously advertised such that more robust midtropospheric height falls may wash across the forecast area late Wednesday night/Thursday morning. This timing would be somewhat unfavorable for momentum transfer of stronger pre- frontal wind gusts into south-central Arizona Wednesday afternoon, and then separated from the pressure gradient post-front on Thursday. Nevertheless, periodic gusts 20-30 mph still looks applicable Wednesday afternoon with stronger speeds preferred near terrain features in the far western CWA

After the initial wave ejects into the plains Thursday/Friday, the flow pattern through the weekend (and perhaps into the beginning of next week) will support mean longwave troughing over the western Conus with a couple negative PV anomalies descending and intensifying from the Pacific NW. The trajectory and depth of the incoming energy suggests a continuation of dry weather for the majority of the forecast area with only slight chances of very light showers over higher terrain areas of Arizona. However, this evolution will yield additional periods of stronger, gusty winds ahead of the shortwave passage along with more pronounced cooling.
In fact, there is moderate to good forecast confidence readings will fall to at least 3F-6F below normal over the weekend with NBM output suggesting nearly a 40% chance Phoenix fails to reach 80F Saturday.

AVIATION
Updated at 2340Z.

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT: No aviation concerns are expected through the forecast period.
Winds have shifted out of the W-SW and will continue to follow light and diurnal tendencies with speeds aob 6 kts at all metro terminals. Other than a FEW passing high clouds, skies will remain mostly clear over the region through early tomorrow.

Southeast California/Southwest Arizona including KIPL and KBLH: No aviation concerns are anticipated during the TAF period. Winds will remain light and follow diurnal patterns with periods of calm and variable expected through tonight. Other than a FEW passing high clouds, skies should remain mostly clear through tomorrow.

FIRE WEATHER
Dry conditions with above normal temperatures will persist early this week with winds steadily becoming more breezy ahead of an approaching weather system. Afternoon humidity levels will continue to fall to around 10% following poor to fair overnight recovery of 20-40%. Cooler weather arriving during the latter half of the week will allow an improvement to RH with afternoon values only falling into a 15-25% range. As this weather disturbance moves through the region later in the week, very breezy conditions will also occasionally impact districts with afternoon gusts commonly reaching 20-30 mph. Given this combination of winds and humidity levels, a periodic elevated fire danger should be planned for during the second half of the week.
