Area Forecast Discussion National Weather Service Tucson AZ 230 AM MST Wed Nov 29 2023
SYNOPSIS
A pair of storm systems will bring a chance of valley rain and mountain snow tonight into Thursday morning, and then again Thursday night into Friday night. Much cooler Thursday into the weekend, with cold overnight lows over the weekend into early next week. Dry and warmer the first half of next week.
DISCUSSION
A storm system near the central California coast will push across Arizona tonight and early Thursday. A chance of valley rain and mountain snow mainly between 03Z-14Z. Initial snow levels around 8500ft early this evening will drop to around 6500ft overnight. Relatively weak dynamics with this open wave with modest valley rainfall amounts and 1 to 3 inches of snow possible above 7k ft.
A stronger system digging down out of the Gulf of Alaska will take a hybrid inland trajectory that should bring another chance of valley rain and mountain snow to the area Thursday night into Friday or Friday night. Some trajectory issues with this part of the pattern with more of a glancing blow possible as some ensemble members are a little shallower and more progressive. At this point we have valley rainfall amounts between .05 and .25 with additional snowfall amounts in the mountains from 2 to 5 inches Thursday night into Friday.
Breezy at times with these systems reinforcing a mean trough position across the area, but nothing close to headlines expected.
Temperatures down 15 to 18 degrees by Friday. If the system is deep enough the cold air advection combined with a drying northwesterly flow may bring the coldest overnight lows of the season so far Saturday morning and/or Sunday morning. This may include a hard freeze for some colder eastern and southern valley locations.
AVIATION
Valid through 30/12Z.
FEW-SCT clouds 8-12K ft MSL, SCT clouds AOA 20k ft MSL. After 30/03Z SCT-BKN 3-6K ft AGL with SCT -SHRA. SFC winds generally southeasterly and less than 12 kts, then becoming west to southwest 8-14 kts AFT 29/19Z. Aviation discussion not updated for TAF amendments.
FIRE WEATHER
A two-part storm system will bring cooler temperatures, breezy winds, and a chance of valley rain and mountain snow showers at times Wednesday night through Friday night or Saturday morning. Clearing and colder than normal Saturday through Monday with a drying trend early next week.
TWC WATCHES/WARNINGS/ADVISORIES
None.
