SHORT TERM. (Today and tonight) Issued at 330 AM MDT Wed Oct 28 2020

Northern Colorado remains under a dry airmass today and still expect some slight warming above yesterdays readings. The upper low which brought snow to our region is now moving eastward across southern New Mexico. The low will continue to track east and northeast through tonight into Texas. The only impact will be some clouds across Southern Lincoln county with any showers staying further south across southeast Colorado. Elsewhere, current satellite and observations showing low clouds/patchy fog across the high mountain valleys again this morning with moisture trapped in low level inversions. Also could see patchy fog along the South Platte River valley.

For the rest of Colorado today, mostly sunny except some high cloudiness that will be working down out of Wyoming. There is a weak wave over the Northern Rockies which will send a weak surge and an increase in northerly winds this afternoon across much of the plains. Surface dewpoints will climb behind this surge and may lead to an increase in fog/low cloud potential later tonight.

Temperatures today will continue to warm as 700mb temperatures slowly climb another couple of degrees c. Temperatures will climb close to 50 degrees especially around Denver with diminishing snow cover. A bit cooler north of Denver and along and north of the S Platte River Basin with lower to mid 30s. Have dropped highs over the high mountain valleys again below mos guidance with continued low level inversions in place for today and tonight.

LONG TERM. (Thursday through Tuesday) Issued at 330 AM MDT Wed Oct 28 2020

Overall, will see a dry pattern, from Thursday thru Sunday as the flow aloft is northwesterly. Temperatures will gradually rise as well Thu and Fri, with readings in the upper 50s to lower 60s, across the plains. The only exception will be across Weld county, where lingering snow cover, may keep readings in the upper 40s to lower 50s.

On Sat, a cool front will move across the plains which may drop highs back into the 50's. Sun will see readings near seasonal normals. By Mon, an upper level ridge will build into the area, with dry conditions and above normal temperatures.

AVIATION. (For the 06Z TAFS through 06Z Wednesday night) Issued at 330 AM MDT Wed Oct 28 2020

VFR with just some high cloudiness moving in today. Weak surge of high pressure will bring some northerly winds into the terminals this afternoon with speeds of 10-18kt. Winds will diminish during the evening with a return to southerly winds overnight. Could see some developing fog later tonight, but for now looks like it will stay north and east of KDEN.

BOU WATCHES/WARNINGS/ADVISORIES. None.

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.
