Area Forecast Discussion
National Weather Service Denver/Boulder CO
248 AM MDT Mon Jun 11 2018

.SHORT TERM...(Today and tonight)
Issued at 248 AM MDT Mon Jun 11 2018

An upper level low moving across southern Canada pushed the upper
level ridge over the area off to the east. Westerly flow aloft
will prevail over the Central Rockies through tonight. A cold
front associated the low to the north raced south across Colorado
last night. This will bring cooler temperatures for today with
highs in the upper 70s to mid 80s across northeast Colorado.
Unfortunately, this system won't increase moisture over the area.
With no increase in moisture and a stable airmass in place, clouds
will have a hard time forming today. It will be windy this
morning over the eastern plains behind the front. Over north
central Colorado, gusty west winds are expected this afternoon and
will increase the fire danger, mainly near the Wyoming border.

.LONG TERM...(Tuesday through Sunday)
Issued at 248 AM MDT Mon Jun 11 2018

On Tuesday, a dry westerly flow aloft will remain over CO with a
ridge of high pressure over New MX and a large trough along the
Canadian border. The models do generate minimal qpf mainly over
the southern part of the cwa in the afternoon and evening.
Temperatures will start to warm up into the mid 80s. Wednesday
through Friday will be the warmest days of the week. The upper
level ridge over the southern U.S. will build northward into CO.
The flow aloft will transition to southwesterly, with some
subtropical moisture advecting into the region. The best shower
and thunderstorm coverage would appear to be late Thursday into
Friday. The fire danger will remain elevated, especially over the
mountain valleys Jackson, Grand, Summit and Park counties. By the
end of the week, an upper level low will be dropping into the
Great Basin from the Pacific Northwest, and the ridge of high
pressure will be over the southern Great Plains. There is some
inconsistency in the models regarding the timing. The GFS is
faster, moving the subtropical moisture into the region by
Saturday. The ECMWF does not do it until Sunday. At least the
trend is similar. Precipitable Water values will be highest over
the weekend and continuing into next week. Weaker flow aloft would
favor thunderstorms with heavier rainfall, especially if remnants
of what left of Bud get entrained into the region. By the
weekend, pw values over cwa may be significantly higher. Values in
the mountains double with values up to 0.75 inches. Across the
northeast plains, values of 1.0-1.5 inches may be possible.

&&

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 248 AM MDT Mon Jun 11 2018

Mostly clear skies will prevail through tonight. Northerly winds
will turn easterly mid to late morning and remain easterly through
00Z. The winds will then become a normal southerly drainage
direction overnight.

&&

.FIRE WEATHER...
Issued at 248 AM MDT Mon Jun 11 2018

A cold front pushed through overnight and will bring some relief
to the very warm and dry conditions. Relative humidities will be a
little higher today, mainly in the teens. Gusty northerly winds
will prevail on the plains this morning. Over the higher terrain
westerly winds will increase this afternoon with the strongest
winds found near the Wyoming border. North Park should see a long
enough duration of gusts greater than 25 mph with relative
humidities less than 15 percent for Red Flag conditions.

The fire danger will remain elevated through the rest of the week
as temperatures increase each day. The driest areas will continue
to be the high mountain valleys where the fire danger will remain
elevated.

AND PALMER DIVIDE EAST TO LINCOLN COUNTY...

This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...Today and Tonight

West to southwest winds will increase over the mountains and
across northeast Colorado today. This combined with very warm
temperatures and very dry conditions will lead to critical fire
danger. Outdoor burning is strongly discouraged, check with local
authorities on any burn bans in effect.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

A dry westerly flow aloft will be over the state on Monday. It
will be cooler with high temperatures closer to seasonal normals.
It will remain dry however and breezy, especially over North Park.
This will keep the fire danger elevated in spite of the cooler
temperatures. Temperatures will gradually warm up through the rest
of the week, reaching the 90s by Thursday.

Late Tuesday through Thursday, subtropical moisture will
gradually increase across the area from the southwest which will
allow for a better chance of afternoon and evening thunderstorms.
The outlook for next weekend appears to be cooler with a better
chance of thunderstorms with wetting rainfall over region.
