.PREV DISCUSSION...306 AM MDT Fri Aug 23 2019...
.SYNOPSIS...
Dry air will continue to push into the state from the west today,
limiting afternoon and evening showers and thunderstorms to the
southwest and northeast portions of the state. Dry and hot weather is
forecast for all areas over the weekend into Monday with near record
to record heat likely for much of the area Sunday and Monday. A cold
front remains on track for Monday night and Tuesday, cooling
temperatures down closer to seasonal averages and resulting in chances
for thunderstorms to eastern New Mexico Tuesday. Shower and
thunderstorm chances shift to the southwest and south-central 
mountains Wednesday and Thursday.

.DISCUSSION...
The south-central and southwest mountains along with the eastern half will
be the favored areas for isolated afternoon and evening showers and 
thunderstorms today while bone dry mid and upper-level air wins out 
elsewhere. A dry weekend remains in store for all areas with near 
record to record heat remaining on tap for Sunday and Monday. Heat
advisories are looking more likely for the east-central and southeast
east plains for both Sunday and Monday. Will hold off another period
or two before deciding on any heat highlights at this point. 

A backdoor cold front remains on track to provide some heat relief 
late- day Monday across the east while the remainder of central areas
see the front pass through Monday night. A cooler airmass moves in 
eastern and central NM Tuesday but temperatures remain near to 
slightly above seasonal averages for late August. Showers and 
thunderstorms continue to look like they will remain hard to come by 
over eastern NM Tuesday and over the southwest and south- central 
mountains Wednesday and Thursday.

GFS continues to be more gung-ho with regard to additional backdoor 
fronts moving in from the northeast Friday into next weekend. ECWMF
has the same general solution with the Four Corner's high centered
over the Desert Southwest and a deep trough over the Upper Midwest
but differs on the strength/depth of the upper trough/low and the
resulting strength of the backdoor front(s). 

While the short-term weather forecast is rather dismal with the lack
of a discernible monsoon, the good news for September and later into
the fall is that a highly positive Pacific-North American (PNA) 
index typically results in a very active northern stream and 
frequent backdoor cold fronts.

.FIRE WEATHER...
A warming and drying trend is underway and will continue through the 
weekend into Monday, bringing well above normal temperatures with 
some record or near-record highs Sun/Mon as an upper level ridge 
strengthens over the region. Hot, dry and unstable conditions will 
expand over the area, with Haines values of 6 forecast across much 
of northern and central New Mexico by Monday. Although humidity will 
exceed critical threshold most areas Sun/Mon, winds will remain below 
critical threshold. A backdoor front will recharge moisture Monday 
night and lead to improved, though unimpressive, chances for wetting 
rain Tue/Wed. A stronger backdoor front may bring better chances for 
wetting rain late next week, but the latest medium range model 
solutions differ significantly with that feature.
