SERVICE.
PLEASE CONTACT OUR OFFICE AT (719) 948-9429, IF YOU HAVE QUESTIONS

DISCUSSION
DISPERSAL FORECASTS ARE TRICKY FOR THIS ONE, AS INVERSIONS ALOFT ARE
LIKELY TO KEEP MIXING HEIGHTS VERY LOW TO THE GROUND AT THE
ELEVATION REFERENCED IN THIS SPOT (11,000FT). THIS WILL MAKE FOR
MATHEMATICALLY VERY POOR DISPERSIONS THROUGH MUCH OF THE DAY
DESPITE THE STRONGER WINDS, ESPECIALLY FOR TUESDAY. WITH ENOUGH
WARMING, IT IS POSSIBLE THAT THAT MIXING HEIGHTS MAY GET HIGH
ENOUGH FOR FAIR OR EVEN BRIEFLY GOOD DISPERSIONS, BUT AT THIS
STAGE IT SEEMS UNLIKELY WITH THE INVERSION ALOFT SET UP. PLEASE
FEEL FREE TO CALL AND ASK FOR AN UPDATE!
OTHER THAN THE UNFAVORABLE DISPERSION FORECAST, BREEZY WEST-
NORTHWESTERLY WINDS ARE EXPECTED, WITH GUSTS TO 25 MPH THIS
AFTERNOON AND GUSTS TO 40 MPH TUESDAY AFTERNOON. WINDS WILL LIKELY
REMAIN ELEVATED STRAIGHT THROUGH THE OVERNIGHT HOURS.
PRECIPITATION IS NOT EXPECTED. HUMIDITY VALUES ARE LIKELY TO
REMAIN IN THE 45% TO 60% RANGE THROUGH THE ENTIRE PERIOD.
