Area Forecast Discussion National Weather Service Tucson AZ 341 AM MST Sat Dec 14 2019

SYNOPSIS. Dry conditions and a warming trend will prevail through today. A weather system moving north of the area may bring isolated showers to the White Mountains Sunday and Sunday night. Then, expect dry conditions but cooler temperatures early next week. Slightly warmer temperatures will return Wednesday and Thursday with even warmer temperatures by Friday and Saturday.

DISCUSSION. Kind of a bummer for the Geminids Meteor Shower. We have excellent viewing conditions and fair temperatures, however that pesky moon is causing problems. If you are headed out for some early morning views, a jacket would still be a good idea.

Expect another beautiful day across southeastern Arizona today. By Sunday afternoon, a shortwave will swing through Arizona with the best energy staying well north of SE AZ. Nonetheless, a few high elevation snow showers and valley rain showers will be possible later Sunday afternoon into early Monday morning across the White Mountains. Otherwise, dry across the remaining areas.

As the system passes to the east, a much cooler airmass will settle into SE AZ beginning Monday. Tucson will struggle to get out of the 50s on Monday. Additionally, expect a chilly start each morning from Monday morning through Wednesday morning. The coldest morning appears to be Tuesday with areas in the Tucson Metro in the middle 30s. Some locations along washes and typical cool spots could make a run at the freezing mark. To complicate the temperature forecast, another southeasterly/easterly wind will set up Tuesday and Wednesday morning. This could help moderate temperatures during the morning as the winds pick up. The winds wont be as strong as past events, but will be noticeably breezy. Temperatures will remain cool most of the week with only a slow moderating trend. However by Friday, warming increases with temperatures well into the 60s Friday for the lower deserts and possibly 70s Saturday. For areas south and east of Tucson, expect upper 50s to lower 60s Friday and lower to middle 60s on Saturday.

Regarding precipitation chances for late next week, confidence is increasing the system will stay well north of Arizona. Thus, everything remains dry in the POP forecast for the entire forecast period.

AVIATION. Valid through 15/12Z. FEW-SCT clouds AOA 25k ft MSL through the forecast period. Surface wind variable in direction and less than 12 kts through 14/18Z, then WLY/SWLY 8-14 kts. Wind becoming southerly 4-10 kts after 15/02Z. Aviation discussion not updated for TAF amendments.

FIRE WEATHER. A weather system moving across the Four Corners region will bring some breezy winds Sunday, especially east of Tucson. This system will also result in a slight chance of sprinkles or flurries in the White Mountains. Dry conditions areawide early next week, but with cooler temperatures. Locally gusty east winds are expected Tuesday and Wednesday of next week.

TWC WATCHES/WARNINGS/ADVISORIES. None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
