000 FXUS65 KTWC 282103 AFDTWC Area Forecast Discussion National Weather Service Tucson AZ 203 PM MST Sun Apr 28 2024 .SYNOPSIS... A warming trend is expected over the next few days as above normal temperatures return by Monday. The forecast remains dry through the coming week, with some afternoon breeziness at times. && .DISCUSSION... After an unseasonably cool Sunday morning, southeastern Arizona will undergo a rapid warming trend over the next few days as mid- level heights rise and a warmer low level air mass moves in. Under sunny skies today (with some lingering clouds around the Whites), high temperatures will be about 8 degrees warmer than yesterday, and then climb another 6 to 8 degrees on Monday reaching into the upper 80s. Southern Arizona remains between split flow through much of this coming week, which keeps temperatures steadily warm but not exceedingly hot either hovering in the upper 80s to lowers 90s. An upper wave should cross well to our north Wednesday-Thursday, which should do little to change temperatures in southern Arizona. This should cause daily breeziness with sustained afternoon winds around 10-15 mph with gusts to 25 mph through the second half of the week with the modestly tightened pressure gradient. Dry weather to continue this week. && .AVIATION... Valid through 30/00Z. SKC throughout the entire forecast period. Northwesterly SFC winds this afternoon around 10-15 kts with gusts to 25 kts. Overnight winds become light and variable. Tomorrow afternoon SFC winds around 8-10 kts from the southwest with gusts to 15 kts.
