Area Forecast Discussion . Updated National Weather Service Phoenix AZ 415 AM MST Thu Oct 1 2020

UPDATE. Updated aviation discussion.

SYNOPSIS. Dry conditions and clear skies will continue into the weekend as strong high pressure persists across the Southwestern United States. Temperatures will remain above normal through the period with lower desert highs generally topping out between 103 and 107 degrees through the end of the week. Slightly cooler temperatures are expected early next week with highs gradually falling back closer to 100 degrees.

DISCUSSION. The unseasonably strong high pressure ridge situated over the Western U.S. has essentially remained unchanged since Monday, but as of yesterday the full strength and heat are now being realized across the Desert Southwest. Highs yesterday tied daily records in Yuma and El Centro, while Phoenix ended up two degrees shy of their record of 107. The ridge is forecast to stay where it is through Friday before weakening into the weekend as a series of weak shortwave troughs begin to move into the Pacific Northwest. Temperatures for today and Friday should again top out near record levels, or anywhere from 105 to 108 degrees with the hottest temperatures across southeast California and southwest Arizona. Overnight lows will remain near normals, keeping overall HeatRisk within the moderate category. Slight weakening of the ridge over the weekend should allow for daily highs to drop around a degree or two per day with highs falling closer to 102-104 degrees by Sunday. Very dry conditions will remain entrenched over the region through the period with surface dew points mostly in the 20s and 30s and PWATs between 0.25-0.50". Skies will remain clear at least through Saturday before some thin cirrus seems likely to move in from the west beginning Sunday as the ridge weakens.

A bit of pattern change is expected for next week, but the overall tendency of a ridge over the western CONUS and a trough in the east is likely to continue. Model spread for the Southwestern U.S. is quite high for the first half of next week as there is potential for a weak cut-off low approaching the region from the west by Monday. For now, the more likely scenario calls for continued above normal temperatures with the weakened ridge mostly staying put over much of the Western U.S. and a weak and mostly dry cut-off low stalling out somewhere west of Arizona. This should keep daily highs around 100 to maybe a couple degrees above 100 across the lower deserts through the first half of next week and dry conditions over the region. No realistic precipitation chances are seen across the region through next week.

AVIATION. Updated at 1115Z.

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:

Strong high pressure aloft will lead to continued clear skies across the central deserts, including the greater Phoenix area, over the next 24 hours. Winds will continue to be light and favor typical diurnal tendencies at the TAF sites. Look for light east wind to return to the west after about 21z, with a few hours of light/variable wind preceding the shift. Overall there are no aviation concerns expected at the TAF sites for at least the next 24 hours and likely far longer than that.

Southeast California/Southwest Arizona including KIPL and KBLH:

Strong high pressure aloft will result in continued clear skies across the western deserts for at least the next 24 hours. Winds will continue to be very light and often variable in nature. Winds at KIPL may favor the west from early evening through the early morning hours. Overall there are no aviation concerns at the TAF sites for at least the next 24 hours.

FIRE WEATHER. Saturday through Wednesday: Dry conditions and well above normal temperatures will continue through the period as high pressure remains in control of the region. Highs near 103-106 degrees on Saturday will gradually cool to 100-102 by Monday under mostly clear skies. Daily minimum RHs will remain low at less than than 10% for most days. Overnight max RH recoveries will be generally between 20-30% in most places. Winds will remain mostly light through the period with a bit of afternoon breeziness.

SPOTTER INFORMATION STATEMENT. Spotters should follow standard reporting procedures.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
