NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Tucson Arizona 
235 PM MST Friday Oct 31 2014 


Synopsis...another warm day to close out October with some 
locations within a degree or two of record highs. A trough will 
bring gusty winds at times through the weekend with significantly 
cooler air early next week. There will be a few showers 
around...mainly on Sunday afternoon. The coldest overnight lows of 
the season so far are expected Monday night into Tuesday morning. 


&& 


Discussion...middle level ridge axis now east of the area with modest 
low level easterly to southeasterly gradient behind it creating some 
gusty winds today...but below advisory levels. This flow combined 
with middle level moisture from the southwest has pushed precipitable 
water values to around .7 or so. Might see a few showers mainly east 
of Tucson this evening. 


Increasing southwesterly flow ahead of a strong West Coast trough 
Saturday. Strongest energy and best moisture lifting into the 
northern plains before the trough axis gets here...however models 
are coming into better agreement bringing a decent secondary impulse 
through central and northern Arizona Sunday. Associated cold front 
will push across Arizona Sunday as well...saving our part of the 
state for last with much of our County Warning Area spends most of Sunday still in 
the warm sector. This would create the unusual situation of places 
like Douglas ending up warmer than Yuma and Phoenix. 


Best enhanced gradient for our area on Sunday...with advisory level 
winds possible for our eastern areas Sunday afternoon. 


Best moisture and dynamics coming together for Phoenix and Flagstaff 
office areas...but we will see a chance of showers as well...mainly 
Sunday afternoon into Sunday evening just ahead of and with the 
front. This will probably include the first snowfall in some High 
Mountain zones with 2 inches or so currently forecast for Hannagan 
Meadow in northern Greenlee County Sunday afternoon and Sunday 
evening as snow levels remain above 8000 feet. 


Much cooler air settling across all of Southeast Arizona by Monday 
with the coldest night of the year so far expected Monday night into 
Tuesday. Coldest Eastern Valley locations could see the first freeze 
of the season...including areas around Willcox and Sulphur Springs 
Valley as well as a few other spots. 


European model (ecmwf) clinging stubbornly to a cut off sagging back into northern 
Mexico just south of US Tuesday into Thursday...wrapping the edge of 
some tropical moisture up from the south as it does so. This is no 
longer quite the outlier it was before with an increasing number of 
European model (ecmwf) ensemble members supporting something like this as well as 
something similar from the new CMC. GFS is even a tad slower and 
deeper than it was before. We are going to massage a little more of 
the 12z European model (ecmwf) into our forecast than we did before...keeping a 
slight chance of showers mainly east and southeast of Tucson and 
slowing the rebound warming trend with the idea that the new ridge 
may be a tad dirtier than we were previously thinking for Wednesday 
and Thursday. 


&& 


Aviation...valid through 02/00z. 
VFR conditions at all terminals. Scattered-broken middle level clouds at 11-15k 
feet above ground level through 01/02...then few-scattered clouds at 8-11k feet above ground level. Slight 
chance of -shra/-tsra east of ktus through 01/08z. Then after 01/19z 
few-scattered cumulus 7-10k feet above ground level with scattered-broken cirrus above. Southeast surface 
wind at 10-15 kts easing after 01/01z becoming southerly 10 kts or less. 
Southwesterly surface wind increasing after 01/17z to 16-22 kts with gusts to 
35 kts. Aviation discussion not updated for taf amendments. 
Cerniglia 


&& 


Fire weather...an approaching low pressure system will bring about 
changing conditions through the weekend. For tonight...there is a 
slight chance of showers and T-storms east of Tucson with easing southeast 
winds. Then the approaching low will generate gusty southwest to 
west winds Saturday and Sunday as it passes north of the area with a 
decent chance of showers Sunday. The winds will also usher in 
significantly cooler temperatures Sunday Onward with the coolest 
readings expected Monday and Monday night with highs in the 60s and 
lows in the 30s to middle 40s. Model trends are now leaning toward 
another low center being in the area the middle of next week for yet 
another threat of showers. Cerniglia 


&& 


Climate...warmest low for the date at Tucson this morning at 
64...beating the old record of 62 from 1987. The low of 55 at 
Douglas ties for warmest. 


Halloween lately has turned out to be a very warm one across 
Southeast Arizona. For Tucson...from 1894 to 2007...there were only 
two halloweens /1916 and 1999/ with highs in the lower 90s. 
Including today (91 as of 2pm)...this is the third time in the past 
seven years /2008 and 2011/ with Halloween highs in the lower 90s.

Twc watches/warnings/advisories...none.
