ACTIVE WEATHER PATTERN WILL CONTINUE THROUGH FIRST PART OF THE
WEEKEND...AS CUTOFF LOW SLOWLY MOVES THROUGH THE NRN PLAINS.
BEST CHANCES FOR SVR WX WILL BE LATE THU AFTERNOON-EVE OVR THE

WILL BE UNDER RIGHT ENTRANCE REGION OF THE STREAK. SURFACE LOW WILL
SET UP SOMEWHERE IN VCNTY OF THE OK PANHANDLE/NE NM. THIS WILL BRING
DEEP MOISTURE OVER EXTREME SE CO...WITH LOWER 50 DEWPOINTS LIKELY
OVR BACA AND PROWERS COUNTIES. STRONG STORMS WILL DEVELOP OVER THE

DIURNAL INFLUENCES ALONG WITH TIMING OF UPPER WAVES...OPTED TO LEAVE
ALL MENTION OF PRECIP AS TSTORMS RATHER THAN SHOWERS. WILL SEE BEST
CHANCES OF PRECIP IN LATE AFTERNOON AND EVENING HOURS...BUT HAVE
MAINTAINED LOW POPS OVR MOST OF THE REGION TO ACCOUNT FOR
