just completed an update. Main changes were for the expiration of
the severe thunderstorm watch and to adjust pops on latest radar
and high resolution model trends. Also adjusted overnight
temperatures. In earlier update had added patchy fog into the
western portion of the area. Also increased cloud cover later
tonight into Sunday morning for expected stratus.

Update issued at 712 pm mdt Sat aug 17 2019
just completed an update. Main change was to adjust pops based on
current trends and also on the hrrr that has been very consistent
in some redevelopment in the next couple hours. So lingered raised
pops in the southern portion of the area where it has been
consistent in this development. Realize currently that not much is
going on now. However, based on the numerous outflow boundaries,
low level jet setting in, and shortwave trough still moving
through, will keep the severe watch going.

Otherwise adjusted hourly trends winds, temperatures, dewpoints,
and sky cover.

Short term (this evening through Monday night)
issued at 234 pm mdt Sat aug 17 2019
the focus for the short term forecast is on the chance of
thunderstorms and the potential for severe storms moving across
the forecast area this afternoon and evening.

With an uncapped atmosphere and good instabilities existing across
the forecast area mainly where surface dewpoints are in the middle
to upper 60s ahead of a surface trough, along with surface
convergence near the surface trough and a short wave trough aloft
approaching in the upper westerly flow, expect the storms
developing over the higher terrain to the west to grow and become
more numerous through the afternoon and into the evening as they
tap into the additional moisture available mainly east of the
colorado border. Expect scattered storms to develop and move
through the area mainly between 3pm-11pm this afternoon and
tonight. While large hail is possible with some of the stronger
storms, the primary threat appears to be damaging winds gusts that
could be 65 mph or greater.

The past few days models have been advertising the possibility of
fog developing across the forecast area in the wake of storms
moving across the region. However, in the latest runs, the
production of fog has diminished with only isolated locations
seeing a possibility of fog. Have removed a mention of fog as a
result, but this will need to be watched over the next few days as
there is the potential of some locations to receive rainfall
followed by clearing skies and light winds that would be conducive
to the production of fog.

Once the short wave trough aloft moves through the region
overnight tonight, an upper ridge will begin to amplify over the
southern rockies and southern and central high plains region
through mid day Tuesday. Also expect mainly high pressure across
the region during that time that will initially cool the
temperatures somewhat on Sunday with highs mainly in the 80s that
will quickly rebound into the 90s on Monday and Tuesday.

Long term (Tuesday through Saturday)
issued at 219 pm mdt Sat aug 17 2019
Tuesday morning, an upper level ridge will extend over the central high plains
with ridge axis just to our west, over the rockies. A surface
high will be in place over the southeastern u.S. And the tri-state
area will be under southwest flow aloft. Through the day, flow
will become zonal over the region and a lee cyclone is expected to
develop Tuesday afternoon. Expected high temperatures will be in
the 90s.

A cold front will move into the area from the north during the day Wednesday.

Temperatures will be cooler with highs in the low to mid 80s and
lows in the 50s and 60s. The cooler temperatures will continue
into Thursday. Showers and thunderstorms will again be possible on
Wednesday. Thursday, additional chances for showers and storms
will be possible as a shortwave moves through the region.

Friday into Saturday, temperatures will rebound back to near
normal, ranging form the mid-80s to low 90s across the area. Lows
will return to the low to mid-60s. Currently not anticipating
precipitation for Friday into the start of the weekend. The ridge
will shift east, over the forecast area. Models are indicating a
possible shortwave moving in from the northwest at the end of the
forecast period, however, taking into account this is seven days
out and disagreement in models, have opted to keep the forecast
dry for now.

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 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.
