...RED FLAG WARNING IN EFFECT FROM NOON TO 10 PM MDT THURSDAY FOR
DRY THUNDERSTORMS FOR THE NORTHERN MOUNTAINS, FRONT RANGE FOOTHILLS,
AND HIGH MOUNTAIN VALLEYS...FIRE WEATHER ZONES 211 THROUGH 218...
.DISCUSSION...Tonight and Thursday...
Hot temperatures and low humidity of 15% or less over the high
mountain valleys, foothills, and I-25 Corridor and nearby adjacent
plains will keep elevated fire weather conditions in place until
early evening. Winds are fortunately staying light, except near
isolated high based showers/storms/virga. The northern mountain
zones of 211, 213, and 217 also have slightly stronger winds with
gusts around 20-25 mph, but under critical thresholds.
On Thursday, critical fire weather conditions will be likely due
to dry lightning. With the slight increase in upper level
moisture, convection should become a little more pronounced.
Of importance, we are uncertain in how extensive the lightning
threat will be, as instability is quite limited. Thus, while
thunderstorms may only be isolated, the dry fuel conditions and
hot/low RH environment will be favorable for new fire starts.
Thus, we`ve opted to upgraded the Fire Weather Watch for the high
country to a Red Flag Warning.
LONG TERM DISCUSSION...Thursday night through Monday...
Friday will still be quite warm and dry in the low levels, but
mid and upper level moisture will increase further. Therefore,
scattered storms with hopefully wetting rains will become more
numerous. There`s still a chance that a few storms could be dry
so we`ll watch this closely. Saturday should feature similar
conditions, but just slight cooling and a little bump in humidity.
Sunday and Monday should see drier conditions return with less
storm coverage, a slight increase in temperatures, and decreasing
humidity.
...Thunderstorms imply strong gusty erratic winds...
...All surface winds are 20-Foot...10-Minute averaged winds...
...CWR is Chance of Wetting Rain - 0.10 inch or more liquid...
...24 HR Trends are based on averages over the respective zone
groups and may not match the actual forecast values
