Area Forecast Discussion National Weather Service Phoenix AZ 1008 AM MST Sun Mar 29 2020

UPDATE. Updated Aviation Discussion.

SYNOPSIS. A warming trend will prevail through Wednesday as high pressure builds across the Desert Southwest. Although somewhat cooler conditions are expected late in the week, slightly above normal temperatures will likely persist.

DISCUSSION. Latest water vapor imagery shows a weak trough along the central California coast. Ahead of this system, widespread mid and high clouds associated with a jet streak currently blanket Arizona. Latest NAM simulated satellite imagery indicates skies will clear this morning, giving way to sunny skies and a continued warming trend. Meanwhile, the aforementioned trough will move through the Mojave Desert today. Main impact will be an increase in wind, particularly across southeastern California, where models suggest gusts could reach 30-35 mph this evening. Across central Arizona, breezy conditions will develop during the late afternoon with occasional gusts up to 15-20 mph.

In the wake of the trough Monday, temperatures will remain a few degrees below normal. A bigger jump in temperatures will occur Tuesday as a ridge builds eastward from the eastern Pacific into the Desert Southwest. Another southern-stream trough will bring abundant high clouds to the region, but the lower-levels will remain too dry for any precipitation.

Models remain in fairly good agreement through Wednesday, depicting a slow-moving Pacific storm system moving into the northern interior West. Southwesterly flow ahead of this system will help to boost temperatures a few more degrees into the upper 80s (across the lower deserts), though again lingering high clouds will temper the heating.

Both the ECMWF-EPS and GEFS have taken a decided turn in the extended period, indicating lower heights associated with the aforementioned trough will linger into at least Friday. Consequently, temperatures were lowered several degrees Thursday-Saturday. Eclipsing the 90 degree mark in Phoenix now appears less likely during the late week period. The warmest ensemble member within the NBM still hints at the possibility of reaching 90 degrees, though a larger spread in the guidance points to increasing uncertainty and the possibility of somewhat cooler temperatures.

AVIATION. Updated at 1710Z.

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT, and Southeast California/Southwest Arizona including KIPL and KBLH:

Area of high clouds will push east of the area this morning leaving generally clear skies through the rest of the period. Winds will generally be light this morning turning west this afternoon with a few breezes possible in the Phoenix area with more steady gusts over the western deserts, including KIPL and KBLH, where gusts of 18-24 kts are expected. Winds tonight for the Phoenix area should stay out of the west a bit longer than typical, but eventually turn back out of the east by 12Z.

FIRE WEATHER. Tuesday through Saturday: High pressure across the Desert Southwest will result in a continued warming trend through Wednesday. Somewhat cooler conditions are likely thereafter as a Pacific storm system affects the northern Great Basin, though temperatures will likely remain above normal. Minimum RHs will generally drop into the mid teens each afternoon. Meanwhile, winds will be on the light side, however localized afternoon breeziness will remain a possibility.

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.
