What forecasters said that day
The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tucson, AZ wrote its last area forecast discussion before this wind advisory went out at Jan 7, 2:59 AM MST, 6 hours 9 minutes earlier.
Area forecast discussion, Jan 7, 2:59 AM MST, 6 hours 9 minutes before
Area Forecast Discussion National Weather Service Tucson AZ 259 AM MST Tue Jan 7 2025 .SYNOPSIS... Mild temperatures and breezy conditions are expected today before a low pressure system begins to move in tonight. Expect much colder temperatures, breezy to windy conditions, and chances for precipitation Wednesday. Although precipitation amounts are expected to be light, the valley floors east of Tucson may be impacted with light snowfall accumulations Wednesday morning. After this system departs, widespread sub-freezing temperatures are expected across Southeast Arizona Thursday and Friday mornings. && .DISCUSSION... Early this morning, a mid-level speed max was digging south over the California coastline. This will drive an associated shortwave to deepen and move over southwest Arizona today, then drop into northern Sonora and Baja on Wednesday. A surface low initially centered in the vicinity of Ajo today will drop south as the upper low closes and becomes vertically stacked. While the main vorticity max will move east on Thursday, a secondary diving impulse will likely reinforce the colder air mass associated with this pattern shift through Friday. Today, high clouds streaming in and breezy winds will be the initial signs of the upstream low. By this evening, strong mid- level height falls will be underway as the upper low settles in over southwestern Arizona. This impressive synoptic setup however will be limited by (at least initially) poor moisture, given the lack of adequate moisture advection and inland track of the low. Steep mid-level lapse rates thanks to the very cold temperatures aloft combined with the strong forcing may be able to squeeze out isolated convection in central to western Pima this afternoon and evening, however given the moisture problem any convective cells should be weak and short- lived. By early Wednesday, guidance begins to show modestly improved moisture advection into southeastern Arizona (generally focused from Nogales-Tucson east and northward). As southeastern Arizona will still remain in the favorable left exit region of the upper level jet, the area should begin to see an increase in precipitation activity. Coverage still remains questionable however as both the southward placement of the upper low (at this point having likely crossed the International Border) and the modest moisture profile will limit more widespread precipitation. In spite of this, crashing snow levels will still bring a chance of light snow to valleys east of Tucson and a slight chance of some light snow mixing with rain in the Tucson metro Wednesday morning. The question still remains whether or not there will be high enough coverage of accumulating snow in eastern areas of the state to necessitate a headline. Additionally, there remains guidance such as the recent NAM, which holds off on precipitation until later in the day Wednesday, reducing the potential for accumulations as temperatures warm. With these factors it remains too early/uncertain for a headline at this time, but the messaging of isolated one to two inch accumulations down to lower elevation areas of Cochise, Graham, and Greenlee counties looks reasonable. Mountain-top snowfall accumulations should remain in the three to six inch range. East to southeast winds are expected to increase late Tuesday night and become strongest Wednesday as the upper low drops through. Current guidance continues to tease wind advisory levels in the Tucson area, Upper Gila Valley, and the far southeastern portions of the state. Widespread 15-25 mph winds with gusts to 35 mph are likely with the higher end areas susceptible to southeast flow likely to see 20-30 mph and gusts up to 45 mph. Finally the greatest impact, especially for the Tucson area, may be freezing morning lows Thursday, Friday, and potentially into the weekend. NBM temperature probabilities continue to be a bit more bullish on the freezing than MOS guidance, but even the warmer MOS puts KTUS right about at the freezing mark. A Freeze Watch remains in effect for Thursday and Friday mornings. Temperatures should moderate back to near normal by the weekend, though with the door open for a few degrees below normal as ensemble height anomalies show signs of weak troughing lingering past the exit of this system. Morning lows near or at the freezing mark again in Tucson can't be ruled out each morning through early next week. && .AVIATION...Valid through 08/12Z. SCT-BKN clouds at 12k-15k feet today. South to southeasterly winds begin to increase today ahead of a low pressure system dropping in from the north. Winds turn and become southeast to easterly after 08/03Z, becoming 15-25 kts by Wednesday morning. An isolated rain/snow shower can't be ruled out tonight as the low pressure system settles in, however higher chances for isolated-scattered rain/snow showers along with lower ceilings arrive after 08/12Z. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER... A low pressure system approaches today and begins to increase winds across southeastern Arizona. Breezy to windy conditions are expected through Wednesday. Widespread 15-25 mph east to southeast winds with gusts to 35 mph are likely early Wednesday through mid- afternoon with areas susceptible to southeast flow likely to see 20-30 mph winds and gusts up to 45 mph. Colder temperatures will bring minimum relative humidities in the lower elevations up from 10-15 percent today to 25-35 percent Wednesday and Thursday. Isolated to scattered rain and snow showers are possible with this low pressure system Wednesday lingering into Thursday, with some light snow accumulations possible in valleys east of Tucson. && .TWC WATCHES/WARNINGS/ADVISORIES...
