focus for most of the thunderstorm activity this evening is mainly
north and east metro denver, so adjusted the pops based off this
trend. Otherwise no other adjustments planned for this evening.

Short term (this evening through Wednesday)

westerly flow aloft continues with a 586 dm ridge over the region. A
weak shortwave embedded in flow aloft combined with diurnal heating
across the high country will continue to bring convection across
the region. Steering flow will push storms ene over the plains
through the late afternoon and evening hours. Dewpoints are in the
upper 40s to lower 50s east of i-25 with better deep layer shear
east of an akron to limon line. Low levels continue to be drier
with near inverted-v soundings and high lapse rates in the low
levels. Main hazards with these storms will be gusty winds up to
45 mph. Some storms may bring some light rain with some small hail
possible over the far northeastern counties. Conditions will
stabilize behind the shortwave bringing partly cloudy to clear
skies and lows into the upper 40s to lower 50s behind the

For Wednesday, a deepening low will drop out of alaska and move
south along the pacific nw. This will put co in more of a SW flow
aloft. Dewpoints over the desert SW are not indicative of monsoon
moisture, so conditions will stay fairly dry. Models indicate
another shortwave in the flow that will push into the region by
Wednesday afternoon. A surface low across the NE plains will help to
pull in some more moisture with SE winds that will set up east of a
sterling to limon line. This will form into a dryline set-up with
slightly weaker deep layer shear. Even without decent shear,
environmental factors could still sustain strong storms capable of
high winds and hail late Wednesday afternoon and into the evening
hours. Temperatures will continue their upward trend with a +1 to
+2c increase from today with highs over the eastern plains close to
or above 90 degrees.

Long term (Wednesday night through Tuesday)
issued at 355 pm mdt Tue jun 25 2019
models have upper ridging building into the CWA from the south
and southeast Wednesday night and Thursday. The upper ridge is
centered over eastern colorado later Friday and Friday night. The
qg omega fields show no synoptic scale energy over the CWA through
Friday night. The low level pressure and wind fields have south-
southwesterly surface winds much of the time. Moisture is fairly
limited through Friday night. The precipitable water values do
come up over the eastern half of the plains later Friday and
Friday night. Looking at CAPE there is some over the eastern cwa
Wednesday evening. The CAPE is higher over the eastern border late
day Thursday, with lesser values over the high country. On
Friday, there is some CAPE over the eastern plains, with small
amounts in the mountains. For pops will go with 10-20%s over the
southwestern CWA late day Thursday and late day Friday. For
temperatures, Thursday's highs are 1-3 c warmer than Wednesday's
highs. Friday's highs will be 0-1 c warmer than Thursday's highs.

For the later days, Saturday through Tuesday, models continue to
show an upper ridge over the CWA all four days with weak west and
southwesterly flow aloft. Moisture increases over the CWA Sunday
through Tuesday so there will be a better chance of late day
showers and thunderstorms those days. Temperatures will stay above
seasonal normals.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 633 pm mdt Tue jun 25 2019
vfr over the next 24 hrs with no restrictions. Gusty southeast
winds at den and apa until 03z, then decrease and transitions to
south southwesterly around 10-12 kts. Winds will increase once
again after 20z Wednesday. Isolated thunderstorms possible mainly
south of denver and could impact apa, but will leave it out of
the terminals at this time. Main impact may be gusty outflow
boundaries that develop from those storms outside of denver.

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.
