Short term...valid for Monday and Tuesday...

Models in good agreement in short term with ridge building over
the region through Monday night...followed by a trough
passage and associated cold front Tuesday evening. Inherited
forecast was in good shape and in need of only limited edits.
Look for highs mainly in the 70s Monday. Possibly near record
temperatures in the 70s to around 80 degrees Tuesday with pre
frontal warming. Our main concern is fire weather conditions for
Tuesday. Lower to middle level winds do not look nearly as strong as
yesterdays did...and the main track of the trough is further north
than yesterdays as we currently do not expect the sharp
cold advection. That said...yesterday was highly unusual and
Tuesday still looks like it could shape up as a critical fire
weather day on its own merits. NAM soundings do mix down some
decent winds Tuesday afternoon and we expect humidity readings to
bottom out again. Therefore...we will continue to headline our
fire weather forecast product and closely monitor Tuesday
parameters. As for high wind potential on Tuesday...again the middle
level wind proggs are nothing like just a typically
breezy to windy afternoon expected Tuesday with the frontal
passage more typical and not worthy of high wind consideration at
this time. Bt

Long term...valid for Wednesday...Thu...Fri...Sat...sun...

Long term proggs have some differences...but overall a fairly
consistent message. Trough exiting the forecast area Wednesday
will leave a cooler cyclonic flow in its wake. Another broader
piece of energy tracks through the Great Basin and central
rockies Thursday...then we see some ridge building Friday into
Saturday. This means an unsettled and cooler extended period for
US...but no significant precipitation as far as we can tell at
this point. Bt



VFR conditions will prevail tonight. No aviation hazards
expected. Chambers
