SYNOPSIS. Very hot daytime temperatures into early next week, with record or near record highs Friday through Monday. Isolated afternoon and evening thunderstorms if they occur will mainly be confined to near the International Border and across the White Mountains.
DISCUSSION. Scattered cumulus across southeast Arizona were generally struggling to overcome a stout inversion noted around H5 on this morning's KTWC RAOB. A few weak echoes were noted across the Chiricahua's and the Huachuca's, with a few better organized cells south of the Int'l Border. A few hi-res CAMs still suggest some additional development this afternoon along the Int'l border adjacent Santa Cruz and Cochise Counties, but confidence remains low in this scenario. Surface temperatures valid 08/22z were running around 1-3 degrees cooler compared to 24 hours ago. We'll have a repeat performance tomorrow, both in the way of temperatures and precip chances as high pressure moves very little over the next day or so.
High pressure then strengthens and builds northward Friday into this weekend, with our forecast of near record to record high temperatures still looking to be on track. That said, and in coordination with neighboring offices, the Excessive Heat Watch for much of southeast Arizona was upgraded to an Excessive Heat Warning from Friday through next Monday. Temperatures this weekend will approach all-time July record highs in some locations. Both GFS and ECMWF 700-850 mb thicknesses suggest Sunday will be the hottest day this weekend, with NBM temperatures continuing to increase but still remaining several degrees cooler than local thickness regressions. Very minor if any changes were made to the inherited high temperature forecast during this impending heat wave period.
Isolated showers and thunderstorms will remain in the forecast each afternoon for a few spots across the CWA, mainly near the Int'l border through Friday and then across the White Mountains this weekend. Upper level flow will become easterly this weekend and southerly next week, which should help usher in some better moisture for convection to develop, however model solutions are still hesitant to commit fully to this scenario. Will still keep slight chance PoPs in the forecast during the afternoon through the middle of next week for mainly higher elevations south and east of Tucson with the thinking that a better monsoon setup is on the way. Temperatures will also come down a few degrees next Tuesday and Wednesday, but still look to be 3 to 5 degrees above normal.
AVIATION. Valid through 10/00Z. Isolated -TSRA/-SHRA this afternoon mostly near the International Border in Santa Cruz and Cochise Counties with brief outflow gusts to near 40 kts possible. FEW-SCT clouds 10k-15k ft MSL this afternoon and evening then some thin cirrus may move in overnight. SFC winds WLY/NWLY 8-12 kts with occasional gusts around 20 kts, decreasing after sundown. Winds less than 10 kts overnight increasing again out of the W/NW at 8-12 kts Thursday afternoon. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Slight thunderstorm chances continue this week, confined along the International Border through Friday. Chances then shift mainly to the White Mountains for Saturday into early next week. Heat remains the primary weather concern with high temperatures approaching or exceeding records in some locations this weekend. 20-ft winds will generally remain less than 15 mph outside of the usual afternoon gustiness due to daytime heating. The strongest winds are expected across the Upper Gila River Valley this afternoon, Thursday, and early next week.

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.
