.SHORT TERM...(Today and tonight)
Issued at 420 AM MDT Tue Apr 3 2018

...Windy early with winds decreasing later today...

Currently...

At 3 am, cold front was along the Raton Mesa and was pushing south.
This boundary was associated with an intensifying surface low over
SW KS. Winds behind the front were quite gusty, with north-northeast
winds averaging 15 to 25 mph with G35. Stronger winds were noted
over the high terrain, especially across the central mtns where
Monarch was gusting to around 60 mph.

A band of light precip was noted over the Palmer Divide extending
into ne CO. A few mtn stations were still reporting light snow.

Temps along and north of the Palmer Divide were in the 30s, with 40s
north of the US-50 corridor and 50s south of the corridor.

Today...

Strongest winds will occur this morning over the plains. Gusts to 60
mph will be possible generally north of a line from extreme eastern
El paso county to La Junta and across northern Prowers county. A
high wind warning is in effect for Crowley and Kiowa county as these
areas should experience the strongest winds. Later today as drier
air moves in on the backside of the low, RED FLAG conditions will
develop. Although the winds will gradually decrease over the plains
this afternoon, winds will still be well above RED FLAG criteria
(>25 mph).

Given the wind direction, any grass fires which develop today will
quickly spread in a general southerly direction.

By late this afternoon, winds across the I-25 corridor will
significantly weaken and will actually become southeasterly at 5 to
10 mph.

As for precip, snow showers will quickly end after sunrise over the
higher terrain. Any light precip over the plains will end prior to
sunrise.

Max temps today will be in the 50s most of the plains with 40s
across northern El Paso county. Warmest temps today will occur over
the San Luis valley with readings well into the 50s.

Tonight...

Generally clear skies will prevail across the region with minimum
temps dropping into the 20s across most of the region. Some teens
will  occur in the central mountains. Southerly winds will pick up a
bit over the northern face of the Raton Mesa with gusts to 25 to
30 mph possible.

.LONG TERM...(Wednesday through Monday)
Issued at 420 AM MDT Tue Apr 3 2018

Wednesday-Wednesday night...Moderate northwest flow aloft continues
across the region with lee troughing progged to deepen across the I-
25 Corridor through the day. This will lead to breezy westerly winds
for areas over and near the higher terrain, especially the Southeast
Mountains and immediate adjacent plains, where dry downslope flow
looks to bring critical fire weather conditions again Wednesday
afternoon. With that said, we have issued a fire weather watch for
the lower elevations of the Sangre de Cristo and Wet Mountains, the
Wet Mountain Valley and the Southern I-25 Corridor, including
Walsenburg and Trinidad. Models are also indicating breezy south to
southwest winds developing across eastern Las Animas County and Baca
County, and have also included these areas in the fire weather
watch. Although afternoon humidity levels will be below 15 percent
across the San Luis Valley, northern portions of the I-25 Corridor
and rest of the Southeast Plains, winds look to be marginal and will
not include in the watch at this time. Otherwise dry conditions and
temperatures warming back to at and above seasonal levels in the 60s
to lower 70s across the lower elevations, and mainly 40s and 50s
across the higher terrain can be expected on Wednesday.

Thursday-Friday...West to northwest flow increases Thursday and
Friday, as a broad upper trough dropping out of Canada digs across
Upper Midwest, as Eastern Pacific energy translates across the West
Coast and into the Great Basin. Latest models indicating slight
chances for a few showers across the Central Mountains Thursday
afternoon, with increasing chances across the higher terrain
Thursday night and across all of South Central and Southeast
Colorado through the day Friday, as the Upper Midwest system sends a
backdoor cold front across the Eastern Plains. Models differ on
timing and location of coldest air associated with Canadian surface
high pressure building across the Plains, with the GFS faster and
much cooler than the ECMWF for Friday across Eastern Colorado, with
blended model solutions also trending cooler and wetter across the
area as well. At this time, went with highs in the 40s and 50s
across the Plains for Friday, coldest across the far southeast
Plains, along with slight chances of showers across the Plains
Friday morning. Scattered showers remain in the offing Friday
afternoon and evening across the higher terrain and immediate
adjacent plains, with continued low level upslope flow.

Saturday-Monday...Latest models continue to indicate Pacific
moisture embedded within increasing westerly flow aloft spreading
across the West Coast and into the Rockies through the weekend. This
will lead to increasing chances of precipitation for areas along and
west of the ContDvd, with moderate to heavy higher elevation
snowfall possible Saturday night and Sunday. Further east, pattern
supports mainly dry, warm and windy weather, with probable high fire
danger across the Eastern Plains, though will need to see where the
main jet core sets up, which could bring a few showers across the
Eastern Mts and Plains. Time will tell.
