western Arapahoe County in northeast Colorado
central Denver County in northeast Colorado
including western Aurora... southern Denver... Englewood... northern
Littleton... central Centennial... Greenwood Village and Sheridan.
* Until 630 PM MDT
* at 513 PM MDT... National Weather Service Doppler radar indicated
heavy rain from a storm over central Denver. This storm was moving
east at 20 mph.
Rain gauges and Doppler radar indicated that 0.50 to 1.30 inches of
rain has fallen over the advisory area from this storm since 4:30 PM
MDT. Pea sized hail can also be expected.
Precautionary/preparedness actions...
Excessive runoff from this storm will cause minor flooding of small
creeks and streams... urban areas... highways... streets and underpasses
as well as other drainage areas and low lying spots.
A Severe Thunderstorm Watch remains in effect until 900 PM MDT Friday
evening for northeastern Colorado.

... The small stream flood advisory remains in effect until 545 PM MDT
for southwestern Weld and northwestern Adams counties...
At 459 PM MDT... National Weather Service Doppler radar indicated
heavy rain 3 miles south of Dacono... or about 21 miles north of
Denver. This storm was moving east at 20 mph.
Locations remaining in the advisory include but are not limited to
northeastern Northglenn... Brighton... Dacono... Fort Lupton... Hudson

Doppler radar estimates that around one to two inches of rain fell
in the area between Brighton... Fort Lupton... and Interstate 25
between 330 PM and 430 PM. Additional rain will fall in this area
from another line of thunderstorms which will continue the threat of
street and small stream flooding.
Precautionary/preparedness actions...
Do not drive your vehicle into areas where the water covers the
roadway as the water depth may be too great to allow your car to
cross safely. Turn around... do not drown.

NWS Forecaster Discussion
339 fxus65 kbou 032050 afdbou Area forecast discussion National Weather Service Denver Colorado 250 PM MDT Friday Jul 3 2009 Short term...short wave currently moving across central Colorado is enhancing showers and thunderstorms across the area. An extra extension of the short wave shown on satellite which was not captured by models is expected to continue this activity through the afternoon and evening. Dewpoints in the 50s and 60s will help with the instability. Moisture from the southwest continues to ride over the ridge to add to the available moisture...contributing to the precipitable water values over an inch this afternoon. Scattered showers and thunderstorms will continue moving off of the mountains and foothills onto the plains this evening. A thermal low over the Kansas and Colorado border will serve as a focus for low level convergence and with enough shear...a chance exists for some thunderstorms to reach severe criteria over the plains especially as the shortwave passes overhead late this afternoon. The shear will allow the storms to possibly produce heavy rain...large hail and strong gusty winds. A Severe Thunderstorm Watch will be in effect this late afternoon and evening for the far eastern plains as a result. A cold front on the back of the shortwave will slide south over northeastern Colorado keeping precipitation chances though midnight...even though good qg descent will be over the forecast area. Precipitation should end shortly after midnight though as the subsident airmass behind the cold front becomes dominant. Upslope flow after the cold front will keep dewpoints in the 50s and 60s over the plains tomorrow. Moisture advected from the southwest will still be over the state as weak upper disturbances bring some weak qg ascent. Another round of scattered showers and thunderstorms are expected in the afternoon and evening. Temperatures will be a few degrees cooler tomorrow from the cold front...but still stay in the lower to middle 80s. Long term...more afternoon and evening showers and thunderstorms can be expected through Sunday. The atmosphere will remain rather unstable with daytime heating and embedded weak disturbances. One such disturbance is now seen over the northern California/Nevada border...and per the q-g vertical motion fields is shown to reach the forecast area Saturday night. This should help storm coverage Saturday evening...while supercell potential and severe weather threat on the plains will be supported by 0-6km bulk shear of 20-25 M/S. On Sunday...both the NAM and GFS want to dry it out along the Front Range and shift the Theta-E axis eastward across the plains. There is some uncertainty with regard to this as high pressure over the Central Plains could promote stronger southeasterly flow and a Denver cyclone which would help the moisture hold in place across most of the Front Range. At this time...will have to broadbrush the area with scattered probability of precipitation given the uncertainty on the mesoscale features and amount of low level moisture. Again...there will be a threat of more severe storms with sufficient shear and instability. By Monday...the airmass should begin to stabilize and warm aloft as upper ridge begins to amplify just a bit. However...we are still in northwest flow aloft so low probability of precipitation are still justified...especially with low level moisture lurking over the plains. Tuesday through Friday will feature much drier and warmer southwest flow aloft. Temperatures are expected to push into the 90s for highs across the plains with 700 mb readings rising to around 20c. Any storms will be high based and produce mainly gusty winds and only light rainfall. Moisture will have a tendency to increase under the ridge so storm coverage may increase just slightly by the end of next week. && Aviation...shower and thunderstorm coverage is expected to increase through 02z...with ceilings overall expected to remain above 6000 feet. Winds will turn northerly around 03z as a cold front slides south over the forecast area. Airmass will dry out after 06z however. && Bou watches/warnings/advisories...none. $$ Kriederman/barjenbruch
