Short term...(today through tonight )
issued at 335 am MDT Tuesday Oct 13 2015

Another warm and dry day is in store as northwesterly flow aloft
continues over the state. Under clear skies...temperatures will
remain above normal for this time of year...with readings in the
upper 70s to lower 80s over the plains and upper 50s to lower 70s
for the mountains. Gusty westerly winds will occur over the
mountains again...with northerly winds over the plains today.
Tonights minimum temperatures will be similar to a few degrees
warmer than this mornings readings.

Long term...(wednesday through monday)
issued at 335 am MDT Tuesday Oct 13 2015

Weather pattern will remain relatively unchanged through Friday
with a blocking ridge dominating our weather. This ridge is caught
in between the stronger northern branch and cutoff low off the
California coast. The ridge is expected to shift only slowly
northward through Friday and Saturday.

In the meantime...dry weather will persist. The only weather
feature will be a back door cold front still on track to push
across the plains Thursday morning with gusty winds but cooler
temperatures behind it. As a result...the much above normal highs
on Wednesday will retreat to closer to normal levels for

By Thursday night...much cooler air will filter in behind the
front. This will bring a threat of patchy frost to portions of the
plains. Slightly cooler air will likely hold over the plains
Friday...before temperatures return to above normal levels over
the weekend as deeper southwest flow develops.

There is some hope of precipitation...albeit late in
the weekend into early next week as the cutoff low is anticipated
to get caught up in the deeper energy reach the West Coast. Models
have struggled with the timing of this will keep the
forecast consistent with a slight chance of showers/storms in the
mountains for Saturday and Sunday...and then possibly spilling
onto the plains by Monday.


Aviation...(for the tafs through 12z Wednesday morning)
issued at 335 am MDT Tuesday Oct 13 2015

VFR conditions through Wednesday morning. Drainage winds early
this morning will veer around to the west then become northerly
around 18z. Speeds are expected to stay below 12 kts...except at
bjc before 12z this morning.

A very dry airmass continues over the state today with minimum relative humidity
values in the low to middle teens. Wind speeds may approach criteria
along the northern state border along and west of i25...however
not enough coverage or length of time to need a highlight.

Grassland fire danger will increase Thursday with the gusty
winds associated with a cold frontal passage...but humidities
will be a little higher than this past sundays event.
