UPDATE. Updated Aviation Discussion.

SYNOPSIS. Beginning today, temperatures will warm to above normal readings under continued dry conditions. A weak upper level disturbance will bring a period of high level cloudiness tonight through the first part of Wednesday before clear to mostly clear skies then dominate through the weekend. Another dry weather disturbance will approach the region late in the weekend into early next week allowing for a gradual cooling trend and a return to slightly below normal temperatures beginning next Monday or Tuesday.

DISCUSSION. Weak upper level ridging over the region will bring additional warming today as highs top out mostly a 82-85 degree range. To the southwest, a weak open trough is evident on satellite imagery well west of Baja. This trough is slated to track northeastward today eventually bringing a decent amount of high level clouds by this afternoon, lasting through the first part of Wednesday before the trough exits to the northeast. Further warming aloft into Wednesday is expected to allow daytime highs reaching into upper 80s across a good portion of the lower deserts. For Thursday through Saturday, zonal to slightly cyclonic flow aloft will continue to bring dry conditions and near normal temperatures to the region.

The broad troughing dominating much of the Western and Central U.S. late this week will eventually influence our region more into early next week as shortwave troughs dipping into the base of the trough push the overall large scale trough farther to the south. Models agree a more significant shortwave diving down the back side of the large scale trough is quite likely Sunday into Monday, but then disagree on how far south the shortwave will reach. Even with the model differences, rain chances across our region should be fairly low, especially across the lower deserts. As far as temperatures, there will most likely be a decent cooling trend during the first half of next week with highs potentially lowering into the middle 70s.

AVIATION. Updated at 1740Z.

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

Minimal aviation concerns anticipated through the TAF period. Winds will favor typical diurnal directions, with speeds remaining below 8 kts through the next 24 hours. Expect winds to become light and variable between transition periods. Otherwise, SCT-BKN high clouds around 20 kft this afternoon will gradually fall to around 16 kft later this evening.

Southeast California/Southwest Arizona including KIPL and KBLH:

Minimal aviation concerns expected through the next 24 hours. Winds at KIPL are expected to remain light and variable through much of today before taking on a light westerly component tonight. At KBLH, winds will mostly remain light and variable through the TAF period, though winds may favor a light southerly component at times during the overnight hours. Expect SCT-BKN high clouds around 20 kft to continue through the period with SCT decks developing around 16 kft this evening.

FIRE WEATHER. Thursday through Monday: The region will remain under a dry pattern through the period with temperatures running around five degrees above seasonal normals through Saturday before a gradual cool down begins. Multiple weak upper level disturbances are expected to pass by the region bringing periods of breezy conditions, but no chances for precipitation. Minimum RHs will generally drop into the teens each afternoon.

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.
