Short term (this evening through Tuesday)
issued at 315 pm mdt Mon sep 16 2019

a longwave trough at mid level was noted just onshore of the pacific
west coast while a ridge was noted over the northern midwest. A
weakening shortwave was deamplifying as it was moving just to the
northeast of the region. The atmosphere was gradually drying out
this afternoon although remnant moisture was still noted over the
mountains and plains, and several showers were noted over the

Over the mountains and valleys it was relatively cool with
temperatures in the 60s in the valleys to lower 40s at mountain top.

Over the plains it was a different story as it was still quite warm
with lower to mid 90s over parts of the far eastern plains and 80s
over the remainder of the lower elevations.

Rest of today and tonight...

best chance of showers will generally in areas west of the sangre de
cristo mountains the rest of this afternoon and early evening. With
the atmosphere relatively cool over the san luis valley (slv), any
storms that get going over the west slopes of the sdc mountains
should be relatively weak and low-end precip producers, so believe
flash flooding threats over the burn scars in the sdc mountains
should be low. Elsewhere, we could see some showers and storms over
the plains, generally east of the sfc trough axis extending from east
of klhx to kim. It is already quite windy east of the trough axis so
any storms that develop out east could produces a svr convective
wind gusts or two later this afternoon.

For tonight... It will remain breezy out east otherwise I anticipate
pretty docile weather over the region. Some showers will be possible
along the contdvd. Temps tonight will range from the 60s over the
far eastern plains, 55 to 60 along the i-25 corridor to 40s and 30s
in the valleys mountains.

For parts of the slv, I cant rule out some patchy ground fog in
places due to the rain that they had last 24 hours or so, but
confidence is not all that high that it will occur.


the mid level trough will be just to the north of NW colorado by
mid day tomorrow as it lift off to the east-northeast. This trough
will increase the gradient aloft significantly and expect winds
at mountaintops tomorrow afternoon to get quite breezy at times,
with gusts to 40 to 50 mph, especially across the central
mountains. Showers will also be on the increase across the contdvd
tomorrow. This trough will push through a pacific front, but do
not see much sensible change in temperatures across the higher
terrain tomorrow as compared to today.

On the plains, we will likely see more Sun tomorrow with westerly
downslope winds by later in the afternoon as the sfc trough moves
across. This should allow MAX temps to be 1 to 3 degrees warmer
tomorrow as compared to today. Precip chances tomorrow on the plains
are pretty low, with the possibility of a fe showers moving over
parts of EL paso county in the afternoon. There will also be a very
low chance of showers over the far southeast plains. \ hodanish

Long term (Tuesday night through Monday)
issued at 315 pm mdt Mon sep 16 2019
initially, precipitation is expected to be on a decreasing trend
Tuesday evening over southern colorado as closed upper low shifts
into north dakota.

Additional rounds of isolated to scattered primarily afternoon
into evening showers and thunderstorms(favoring higher terrain
locations) are anticipated from Wednesday into Friday as
relatively weak upper disturbances rotate across the CWA during
this time-frame.

In addition, gradient winds are expected to increase Friday,
helping to enhance the fire weather threat on Friday. WFO pueblo
will continue to closely monitor latest trends and issue fire
weather highlights as warranted.

Then, generally dry southwesterly to zonal upper flow is expected
to develop over the majority of the CWA from Saturday into
Monday, allowing for basically dry and breezy conditions over the
majority of cwa(with the possible exception of northern locations
Saturday night, where a northerly component surface surge will be
capable of generating precipitation) in combination with elevated
fire weather concerns at times.

Above seasonal mid-september temperatures are expected to continue
from Tuesday evening into Friday night, followed by cooler
temperatures(although still near to slightly above seasonal
averages) over the majority of the CWA from this weekend into
next Monday.

Aviation (for the 00z tafs through 00z Tuesday evening)
issued at 315 pm mdt Mon sep 16 2019
vfr next 24 hours at kcos, kpub and kals. Winds should be relatively
light, and mainly from a SW component during the afternoon tomorrow.

There is a low chance of some ground fog at kals tomorrow morning
towards sunrise, but risk appears pretty low at this time.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
