AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
210 PM MDT (310 PM CDT) FRI MAY 22 1998

...MAIN FCST CHALLENGE IS CONVECTION TONIGHT...

ETA AND AVN INITIALIZED WELL...BOTH WERE EXCELLENT AT 5H. ETA/AVN
WERE BOTH GOOD AT SFC...WHILE NGM WAS TOO DEEP ON THE LOW OVER KS AT
12Z. BY 18Z ETA WAS BEST AT SFC AS IT INDICATED DEVELOPING LOW OVER
EASTERN COLORADO. WILL FOLLOW ETA THIS PACKAGE.

WV SATELLITE SHOWS A VORT MAX MOVING INTO CENTRAL CO WHICH IS FIRING
TRW ALONG THE FRONT RANGE. THIS FIRST WAVE WILL TRIGGER CONVECTION
OVER WESTERN SECTIONS OF FA BEGINNING LATE THIS AFTERNOON THROUGH
THE EVENING. WITH SFC LOW DEEPENING OVER EASTERN CO LATE THIS
AFTERNOON...MOIST UPSLOPE FLOW WILL PRODUCE BEST MOISTURE
CONVERGENCE FROM NE CO ACROSS NORTHERN AND EASTERN SECTIONS OF FA.
Q VECTOR ANALYSIS SHOWS STRONGEST CONVERGENCE OVER THETA E RIDGE
ACROSS EASTERN FA BY 00Z. WENT HIGHEST POPS NRN AND ERN FA FOR THESE
REASONS.

UPSLOPE FLOW CONTINUES FOR MOST OF THE NIGHT. THIS COMBINED WITH
SOME OUTFLOW COOLED AIR OVER FA...SO EXPECT AREAS OF FOG TO DEVELOP
OVER ALL BUT FAR SRN ZONES. WITH CLOUDS AND E WINDS MOST OF THE
NIGHT...TEMPERATURES SHOULD STAY ABOVE FWC/FAN NUMBERS.

UPPER LEVEL LOW KICKS OFF TO THE NORTHERN PLAINS ON SAT...DRAGGING
THE SFC LOW INTO EASTERN KS. NORTHERLY WINDS WILL SPREAD ACROSS FA
EARLY SAT MORNING. ALTHOUGH Q VECTOR ANALYSIS INDICATES BEST FORCING
OVER EASTERN KS BY 12Z...THINK THAT WRAP AROUND MOISTURE WILL
CONTINUE WIDELY SCATTERED CONVECTIVE ACTIVITY SAT MORNING OVER
EASTERN ZONES.

PRECIPITATION ENDS BY SAT AFTERNOON WITH DRY CONDITIONS FOR THE REST
OF THE PERIODS. CAA BEHIND SFC LOW KEEPS 850/700 THICKNESSES 30M
LOWER THROUGH SUN AFTERNOON PER ETA/AVN. PREFER FAN NUMBERS OVER
SLIGHTLY WARMER FWC.
