Area Forecast Discussion National Weather Service Tucson AZ 212 PM MST Thu Sep 23 2021
SYNOPSIS. Chances for showers and storms will continue into early next week as a pair of systems impact the area. High temperatures will mostly be several degrees below late September normals.
DISCUSSION. A remnant MCV is taking on a life of its own today, as it lifts from northern Sonora into southeast Arizona. Heaviest rainfall amounts have been less than 1/2 inch with most locations under 1/10. Tucson airport is still struggling to climb into the 80s this afternoon with all of the cloud cover across most of SE AZ. Moisture trends are up as expected, with satellite precipitable water estimates ranging from 1.1 to 1.35 inches across the area. Surface dew points are up 10 to 15 degrees over the past 24 hours, putting most of the area back into the 50s. All part of a broad low developing over the region as additional energy splits down from the north over the next several days.
As this low shifts toward New Mexico over the next 12 hours, a split digging down out of southern Idaho and northern Utah will reinforce a broad mean low position across southern California and Arizona Friday. That will probably mean a break in precip chances as the main low center consolidates near northern Baja. The increasing southerly flow from Sonora into southern Arizona will draw in a longer fetch of moisture for the weekend. Saturday looks very interesting with an upper level diffluent field across SE AZ potentially assisting storm development.
The main low is expected to shift slowly through Arizona Sunday and Monday, however it may slow down a bit as it loses higher latitude support. That would put Sunday as prime time for the best moisture/dynamics couplet across SE AZ, but watch for Monday as well if things slow down.
The mean trough position over the southwest will continue next week with ensembles dropping another split down from the north around the middle to second half of the new week. Timing on that is problematic at this point, but it should serve to help keep temperatures below climo through most of next week.
AVIATION. Valid through 25/00Z. SCT-BKN clouds at 10k- 14k ft MSL ISOLD-SCT -SHRA/-TSRA. SFC wind variable in direction at less than 12 kts, gusty at times with thunderstorm outflows. Aviation not updated for TAF amendments.
FIRE WEATHER. Isolated to scattered showers and thunderstorms this afternoon, with the chance of precipitation persisting through the weekend into early next week. RH values will remain above critical thresholds and 20-foot winds will generally be less than 15 mph.
TWC WATCHES/WARNINGS/ADVISORIES. None.
