.SHORT TERM...valid for Tdy and Tue...

An upper ridge will take hold of the northern Rockies through
Tuesday. This will provide a warming trend as temperatures rise
above seasonal averages. The warmest day will be Tuesday courtesy
of prefrontal warming. Highs on Tuesday will be in the lower to
mid 80s. The forecast will be dry with the ridge in place. A cold
front will push in from the north Tuesday night and provide a
slightly cooler day Wednesday. TWH

.LONG TERM...valid for Wed...Thu...Fri...Sat...Sun...

Little in the way of changes for the extended period...as models
remain in reasonably good agreement on generally blocked pattern
to start the period...followed by a return to unsettled pattern.
Expect to see daytime temps well above seasonal average
throughout the bulk of the period...with highs in the 70s to near
80 degrees into the weekend. Cooler weather again to end the
extended period.

Generally dry conditions will prevail Wednesday and
Thursday. Southwest flow will bring monsoonal moisture into the
area...and begin increasing pwats across the region. Monsoonal
flow stays in place through Friday and Saturday...keeping PWATS
unusually high. Several pieces of energy rotate through the flow
during this period...but dry conditions across the plains...and
generally weak impulses keep isold shower and thunderstorm
development confined to high terrain and nearby foothills through
Friday night. A stronger wave...and associated cold front push
across the region beginning Saturday...and crossing through
Sunday. Saturday night appears to be our best shot at appreciable
moisture through the period. Although models point to a bit of a
break before the significant wave crosses the region...a broad
trof will remain in place over the region...so have kept slight
pops in place at this time. AAG
