SIGNIFICANT WEATHER OUTLOOK FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER CO
11 AM MDT   WEDNESDAY   JULY 19 1995

THIS OUTLOOK PERTAINS TO THE FOLLOWING COLORADO COUNTIES

ADAMS      ARAPAHOE    BOULDER       CLEAR CREEK    DENVER      DOUGLAS
ELBERT     GILPIN      GRAND         JACKSON        JEFFERSON   LAKE
LARIMER    LINCOLN     LOGAN         MORGAN         PARK        PHILLIPS
SEDGWICK   SUMMIT      WASHINGTON    WELD

SYNOPSIS:  A WEAK COLD FRONT HAS MOVED THROUGH MOST OF THE AREA THIS
MORNING AND WILL BE INTO SOUTHEASTERN COLORADO BY 1 PM MDT.  NORTHERLY
WINDS 10-15 MPH AND SLIGHTLY COOLER AIR HAS MOVED INTO THE AREA BEHIND
THIS FRONT.  THE NORTHERLY WINDS WILL ALSO REDUCE RELATIVE HUMIDITIES A
LITTLE ALONG THE FRONT RANGE AND I-25 AREA...HOWEVER THE AIRMASS FROM
ABOUT A FORT MORGAN-LIMON LINE WILL REMAIN VERY MOIST.  THE LOWER
HUMIDITIES WILL REDUCE THE THREAT OF THUNDERSTORMS SLIGHTLY ALONG THE
FRONT RANGE BUT SCATTERED THUNDERSTORMS ARE EXPECTED AGAIN FROM FORT
MORGAN EAST WHERE THE AIRMASS WILL BE UNSTABLE ENOUGH SO THAT SOME OF
THESE THUNDERSTORMS MAY BECOME SEVERE WITH LARGE HAIL.  THUNDERSTORMS
WILL BE MOSTLY AFTER 2 PM MDT EXCEPT IN SEDGWICK AND PHILLIPS COUNTIES
WHERE A FEW THUNDERSTORMS MAY FORM BY NOON ON THE TAIL END OF A WEAK
UPPER LEVEL DISTURBANCE.  ANOTHER UPPER LEVEL DISTURBANCE WILL ALSO
BRING SCATTERED THUNDERSTORMS TO LARIMER COUNTY BY NOON.

WINDS ALOFT HAVE INTENSIFIED IN THE PAST 24 HOURS THEREFORE THE
THUNDERSTORMS THAT DO FORM WILL MOVE AT A FASTER CLIP REDUCING THE
THREAT OF HEAVY RAIN AND LOWERING THE POTENTIAL FOR ANY STREET OR SMALL
STREAM FLOODING.  IT APPEARS THAT MAXIMUM RAINFALL AMOUNTS WILL BE
1 INCH OR LESS.

SPOTTER ACTIVATION IS NOT ANTICIPATED SINCE THE THREAT OF SEVERE WEATHER
APPEARS TO BE MAINLY EAST OF FORT MORGAN...HOWEVER SPOTTERS ALONG THE
FRONT RANGE SHOULD BE ALERT IN CASE THINGS DO BLOW UP IN THE AFTERNOON.

...THUNDERSTORMS FORMING ALONG THE FRONT RANGE...

THE FIRST THUNDERSTORMS OF THE DAY HAVE BEEN DETECTED ALONG THE FRONT
RANGE OF COLORADO FROM LARIMER COUNTY THROUGH BOULDER TO JEFFERSON
COUNTY.  MOST OF THE THUNDERSTORMS ARE RATHER WEAK AT THIS
TIME...HOWEVER ONE THUNDERSTORM IN LARIMER COUNTY HAS BECOME STRONG
ENOUGH TO POSSIBLY DROP SMALL HAIL AND MODERATE TO HEAVY RAIN.  A FEW
SHOWERS WERE NOTED IN SEDGWICK AND WELD COUNTIES AS WELL.

AT 1155 AM MDT THE STRONG THUNDERSTORM WAS LOCATED ABOUT 16 MILES WEST
OF FORT COLLINS COLORADO.  IT WAS MOVING TO THE EAST ABOUT 20 MPH AND
IS EXPECTED TO WEAKEN AS IT MOVES OFF THE FOOTHILLS INTO THE PLAINS.

WHILE CONDITIONS ARE STILL RIPE FOR THE DEVELOPMENT OF THUNDERSTORMS...
WINDS ALOFT HAVE INCREASED SO THAT THEY WILL BE MOVING FASTER THAN THE
PREVIOUS FEW DAYS REDUCING THE THREAT OF STREET AND SMALL STREAM
FLOODING.  EARLY ESTIMATES POINT TO MAXIMUM RAINFALL AMOUNTS OF ABOUT
1 INCH PER HOUR FROM THE HEAVIEST THUNDERSTORMS FOR MOST AREAS ALONG AND
NEAR THE FRONT RANGE AND I-25 CORRIDOR.  FURTHER EAST NEAR THE KANSAS
BORDER RAINFALL AMOUNTS MAY BE  A LITTLE HEAVIER DUE TO THE AIRMASS
HAVING MORE MOISTURE THERE.

WHILE THE THREAT OF SEVERE THUNDERSTORMS ALSO APPEARS TO BE A LITTLE
LOWER NEAR THE FRONT RANGE THIS AFTERNOON...THERE IS STILL A RISK THAT
SOME THUNDERSTORMS MAY PRODUCE LARGE HAIL THIS AFTERNOON BUT MAINLY
EAST OF A LINE FROM FORT MORGAN TO LIMON.

...SHOWERS AND THUNDERSTORMS IN NORTHEAST COLORADO...

A BAND OF SHOWERS WAS MOVING ACROSS THE EASTERN METRO DENVER-AURORA
AREA AT 1230 PM MDT.  THIS BAND OF SHOWERS DROPPED .40 INCHES OF
RAIN AT THE INTERSECTION OF MONTVIEW AND CHESTER IN AURORA WHILE THE
NATIONAL WEATHER SERVICE OFFICE RECEIVED .05 INCHES OF RAIN.

SHOWERS AND THUNDERSTORMS WERE ALSO DETECTED OVER THE FRONT RANGE
FOOTHILLS...ESPECIALLY IN LARIMER COUNTY.  THE THUNDERSTORMS IN
LARIMER COUNTY FOOTHILLS WERE STRONG ENOUGH TO PRODUCE MODERATE
RAIN AND PERHAPS SMALL HAIL.  THE SHOWERS AND THUNDERSTORMS WERE
MOVING EAST ABOUT 20 MPH AND WERE WEAKENING RAPIDLY AS THEY MOVED OFF
THE FOOTHILLS TOWARDS THE I-25 CORRIDOR.

A BAND OF MODERATE THUNDERSTORMS WAS ALSO MOVING EAST ACROSS PHILLIPS
COUNTY.  THESE WERE CAUSING SOME MODERATE RAIN AND POSSIBLY SMALL HAIL.
THEY WERE MOVING EAST ABOUT 25 MPH AND WILL BE INTO THE KANSAS AREA BY
130 PM MDT.

CONDITIONS ARE RIPE FOR THE DEVELOPMENT OF THUNDERSTORMS BUT WINDS ALOFT
HAVE INCREASED SO THAT THEY WILL BE MOVING FASTER THAN THE PREVIOUS FEW
DAYS REDUCING THE THREAT OF STREET AND SMALL STREAM FLOODING.  EARLY
ESTIMATES POINT TO MAXIMUM RAINFALL AMOUNTS OF ABOUT 1 INCH PER HOUR
FROM THE HEAVIEST THUNDERSTORMS FOR MOST AREAS ALONG AND NEAR THE FRONT
RANGE AND I-25 CORRIDOR.  FURTHER EAST NEAR THE KANSAS BORDER RAINFALL
AMOUNTS MAY BE  A LITTLE HEAVIER DUE TO THE AIRMASS HAVING MORE MOISTURE

A THREAT OF SEVERE THUNDERSTORMS ALSO EXISTS BUT MAINLY EAST OF A LINE
FROM FORT MORGAN TO LIMON.

STAY TUNED TO NOAA WEATHER RADIO AND LOCAL NEWS MEDIA FOR THE LATEST
WEATHER FORECASTS AND BULLETINS.  WATCH WEATHER CONDITIONS AND MOVE
INDOORS IF THUNDERSTORMS APPROACH YOUR AREA.  REMEMBER AND FOLLOW THE
SAFETY RULES PERTAINING TO LIGHTNING AND OTHER SEVERE WEATHER.

...THUNDERSTORMS CONTINUE IN NORTHEAST COLORADO...

SCATTERED THUNDERSTORMS CONTINUE OVER NORTHEAST COLORADO BUT ARE MOSTLY
OF LIGHT TO MODERATE INTENSITY.

RADAR INDICATES THAT THE STRONGEST CELL WAS OVER EASTERN LINCOLN COUNTY
ABOUT 24 MILES EAST OF LIMON.

LINE ABOUT 4 MILES SOUTH OF DEERTRAIL OR 50 MILES NORTHWEST OF LIMON.

NORTH OF CENTRAL CITY OR 55 MILES WEST OF DENVER.

THE THUNDERSTORMS ARE PRODUCING MODERATE TO BRIEF HEAVY RAIN AND PERHAPS
SOME SMALL HAIL.  THE THUNDERSTORMS WERE MOVING TO THE EAST AT 20-25 MPH
SO THAT THE THREAT OF STREET OR SMALL STREAM FLOODING DUE TO SLOW MOVING
THUNDERSTORMS IS QUITE LOW.
