.SHORT TERM...(Today and tonight)
Issued at 425 AM MDT Mon Jun 24 2019

Drier and much warmer conditions will prevail today as an upper
level ridge begins building over the state and dry westerly flow
aloft prevails. Temperatures won`t quite reach the seasonal
normal, but afternoon highs around 80 will sure feel a lot warmer
than the weekend that just passed. Skies should be mostly sunny
except for some lee wave clouds along and east of the Continental
Divide. The mountains and Palmer Divide may see a few showers
develop through the afternoon hours, just because there will be
strong heating from the sun and the developing upper ridge will
not have enough subsidence to quell the diurnal pattern of
building thermals. Only light precipitation amounts will result
from the few showers that develop. Tonight should see mostly clear
skies prevail with temperatures dropping to a few degrees below
normal.

.LONG TERM...(Tuesday through Sunday)
Issued at 425 AM MDT Mon Jun 24 2019

The weather for the upcoming week will be characterized
by warming temperatures and generally dry conditions. The exception
will be isolated late day showers and thunderstorms, especially over
the mountains, higher terrain areas and portions of far eastern
Colorado.

For Tuesday, the flow will be more westerly with enough moisture in
the mid and upper levels for isolate day showers and storms.
Forecast soundings showing inverted-v type profiles resulting in
impacts of gusty winds but little rainfall. Temperatures will
continue to warm as 700mb temperatures climb to around +12 and
resulting in afternoon temperatures in the mid 80s.

For Wednesday through Friday, a strong low pressure area will park
itself along the Pacific northwest coast and a resultant southwest
flow aloft over Colorado. This will result in further warming and
expect afternoon highs will top the 90 degree mark for Thursday and
Friday across lower elevations. There will be some return of low
level moisture across the eastern plains as low level flow shifts
more southeasterly. Forecast models showing a dry line evolution
by Wednesday afternoon which could focus convection on the far
eastern plains with CAPE values exceeding 2000j/kg. SPC also has
far eastern Colorado under a marginal risk of severe storms. Will
indicate some higher pops in this region as well.

By this weekend, the southern high plains ridge will be well
entrenched and appears to begin to tap deeper moisture back into
eastern Colorado. Expect a bit better storm coverage during the
afternoon and evenings while temperatures remain quite warm.

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 425 AM MDT Mon Jun 24 2019

No aviation impacts this morning as skies remain clear or mostly
clear and drainage southerly winds continue. This afternoon should
see some high level clouds and winds switching to west or
northwest. Winds may gust up to about 20 knots for a little while
late in the afternoon. No aviation impacts tonight.
