UPDATE. Aviation Section Updated
SYNOPSIS. High pressure under mostly clear skies will bring slightly warmer daytime temperatures through Saturday as highs climb to around 70 degrees each day. A weak but mostly dry weather system for Sunday into Monday should bring cooler temperatures into early next week with readings closer to seasonal normals.
DISCUSSION. Thick high clouds have been pushed off to our east, as a weak shortwave quickly moves across the eastern half of Arizona. High pressure will continue to build into the region in the wake of this shortwave and result in a warming trend through the first half of the weekend, with highs in the low 70s forecast on Friday and Saturday.
For the remainder of today, expect mostly clear skies during the daylight hours with temperatures across the lower deserts rising into the upper 60s. After sunset, another batch of high clouds will move into the area from west to east, and remain in place through much of the day tomorrow before clearer skies take over Friday.
The second weather system will move across the region Saturday night through Sunday and bring slightly elevated rain chances back to the forecast, especially across the western portions of JTNP Saturday night/Sunday morning and across southern Gila county Sunday afternoon. Still looks unlikely that the lower deserts will see any rain from this system, but a light shower and/or virga cannot be ruled out and GEFS plumes continue to indicate that Sky Harbor could see up to a hundredth of an inch of rain Sunday. Impacts with this system should be minimal and the most noticeable outcome will be the lowering of temperatures Sunday and even more so on Monday. It looks like high pressure will once again build into the region in the wake of this weather system, resulting in a slight warming trend as we head into the middle of next week.
AVIATION. Updated at 2320Z.
South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:
No aviation concerns through the TAF period. Mostly clear skies will transition to scattered coverage as another batch of thicker high clouds aoa 20 kft moves into the region overnight. Wind speeds will be very light and directions will favor typical diurnal tendencies but with long periods when the direction will be variable.
Southeast California/Southwest Arizona including KIPL and KBLH:
No aviation concerns through the TAF period. Mostly clear skies will transition to scattered-to-broken coverage as another batch of thicker high clouds aoa 20 kft moves into the region overnight. Look for very light winds over the next 24 hours at KIPL and KBLH.
FIRE WEATHER. Friday through Tuesday: Dry conditions under increasing high pressure aloft will prevail through Saturday before a weak low pressure system affects the region Sunday into Monday. Moisture levels with the late weekend system should be rather dry, hindering precipitation chances although there is a slight chance of rain or high elevation snow Sunday afternoon and overnight Sunday night over high terrain east of Phoenix. Above normal high temperatures Friday and Saturday give way to somewhat cooler conditions Sunday into early next week as highs fall slightly below normal by Monday. Minimum humidity levels initially should stick around 25-35% much of the period, potentially lowering slightly into early next week. Winds will stay light through Saturday before some breezy conditions move in for Sunday and Monday. Light winds return again Tuesday as weak high pressure aloft returns to the area.
SPOTTER INFORMATION STATEMENT. Spotters should follow standard reporting procedures.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
