have lowered the pops along the urban corridor this evening as the
main band of showers has shifted to the east. Secondary wave of
showers could move through later so will keep slight chc pops in
the grids to account for this. Light snow showers still likely
in the mountains through the remainder of the evening, especially
along west facings slopes. Threat of thunderstorms appears to
have passed, at least for our cwa, so have dropped that from the
forecast. Strongest storm at this time north of the co line along
the wy NE border with another south of lincoln county.
Short term (this evening through Monday)

will be keeping an eye on the scattered showers and possible
thunderstorms moving out of the mountains through this evening.
Temperatures are expected to remain warm enough that the showers
on the plains remain liquid. Have not observed any lightning over
the state so far this afternoon, but the airmass may still de-
stabilize enough for a few thunderstorms. The trough axis is
evident on satellite imagery coming over the western colorado
border at this time. Flow at mid and upper levels is forecast to
increase through this evening, keeping the short wave trough
moving eastward overnight.
After the trough passes through tonight, heights over the state
will begin rising as an upper ridge builds in from the west.
Temperatures will begin warming up across the forecast area under
mostly sunny skies. Subsidence under the building ridge will cut
off precipitation across the state, including over the mountains.
Long term (Monday night through Sunday)|

models have upper ridging over the CWA Monday night through
Tuesday. Then there is southwesterly flow aloft Tuesday night
through Wednesday night. The QG omega fields keep benign synoptic
scale energy over the CWA Monday night through Wednesday evening.
The low level winds look to adhere to fairly normal diurnal
patterns all five periods. Moisture wise, it looks sparse through
Wednesday. There is a bit of upper level moisture here and there.
There is no measurable precipitation on the QPF fields through
Wednesday night. No pops. For temperatures, Tuesday's highs are
up 5-7 c from Monday's highs. Wednesday's highs are 1-2 c warmer
than Tuesday's. For the later days, Thursday through Sunday,
models show more southwesterly flow aloft on Thursday. An upper
trough closed low is over colorado on Friday into Saturday. Then
there is upper ridging on Sunday. The medium models are all over
the place concerning precipitation for the CWA from late Thursday
into Friday night. After above normal temperatures on Thursday, a
cold front moves in that evening and Friday through Sunday have a
colder than normal airmass in place.
Aviation (for the 06z tafs through 06z Monday night)
issued at 912 pm mdt Sun mar 24 2019
vfr expected the rest of tonight through Monday evening. Light
southeasterly winds will continue to transition to drainage the
rest of this evening. Expect northwesterly winds to develop late
Monday morning then transitioning to northeast winds in the
afternoon. Winds speeds should generally stay below 10 kts.

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.
