Utah and northwest Colorado. Lighter winds and scattered
showers/thunderstorms return Sunday. Shower coverage will be highly

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.
.DAY ONE...This Afternoon and Tonight
A dryline will set up this afternoon over the far eastern plains,
leaving conditions favorable for strong to severe storms. However,
storms will have to overcome a stable layer of air to form, making
chances for storms much less likely, typically 15 percent or less.
If storms do manage to form, they could quickly become strong to
severe, producing winds in excess in 65 mph and hail up to 1.5
inches in diameter. An isolated tornado near the Kansas border can
not be ruled out.
Critical fire weather conditions are expected across the higher
terrain today as well, though fuels are still too green to warrant
any fire weather highlights at this time.
.DAYS TWO THROUGH SEVEN...Saturday through Thursday
A few strong to severe storms will be possible on Saturday
afternoon and evening, from the Palmer Divide, southeast across
the Plains. Large hail and damaging winds may be possible with
stronger storms, especially across the Palmer Divide region.
Showers and thunderstorms, some possible strong to severe, are
forecast for Sunday into Monday, initially developing along the
Eastern Mountains, and tracking south and east across the Plains.
Stronger storms will be capable of producing large hail and
damaging winds.
Daily afternoon and evening showers and thunderstorms will
continue Tuesday through Friday. Activity will develop over the
Mountains, then spread east across the Plains during the evening.
A couple of storms during this period could become strong.
.SPOTTER INFORMATION STATEMENT...
Weather conditions that meet reporting criteria for spotters will
be possible over portions of the region.

This hazardous weather outlook is for northeast and north central
Colorado.
.DAY ONE...Today and Tonight
A couple strong to severe thunderstorms will be possible this
afternoon across far northeastern Colorado, mainly along and east
of a line from Sterling to Akron. Large hail and gusty winds will
be the main threats from storms this afternoon.
Across the Denver metro, dry weather is expected with highs in the
mid 80s.
.DAYS TWO THROUGH SEVEN...Saturday through Thursday
Coverage of showers and thunderstorms will increase Saturday,
with a few severe storms possible along the Front Range into the
eastern plains. Scattered to numerous showers and storms can then
be expected through Sunday, but cooler weather will likely limit
instability and any severe storm threat. Memorial day should see a
little lower shower and storm coverage, with temperatures
remaining a few degrees below normal.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today or tonight, but any
reports of hail or wind will be appreciated.
