Area Forecast Discussion National Weather Service Tucson AZ 223 AM 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.

Southern Arizona remains between split flow through much of this coming week, which keeps temperatures steadily warm but not exceedingly hot either. 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 however through the second half of the week with the modestly tightened pressure gradient.

FIRE WEATHER
High temperatures will be 3-5 degrees below normal today, warming to 3-7 degrees above normal Monday through the rest of the week. 20-foot winds will be below 15 mph most of this week, with afternoon gustiness due to strong surface heating. The strongest winds appear to be on Wednesday, with southwest winds at 15-20 mph and gusts to around 30 mph. Min RH values in the valleys will be in the 10-15 percent range today, decreasing into the single digits this week.
