AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
345 AM CST TUE JAN 16 2007

.SYNOPSIS...
A BITTER COLD START WILL BE IN THE OFFERING TODAY AS THE ARCTIC
HIGH STRETCHES FROM ONTARIO CANADA SOUTHWEST...TO SOUTHERN TEXAS.
THE ELONGATED RIDGE OF HIGH PRESSURE BUILDS SOUTHEAST TO ALLOW
RETURN FLOW TO DEVELOP THIS AFTERNOON. CLOUDS TOPPING THE UPPER
RIDGE AND SPREADING SOUTHEAST WITH FEW HIGH CLOUDS CLIPPING THE
NORTH TODAY.

.SHORT TERM ...(TODAY-THURSDAY NIGHT)
TEMPERATURES WILL BE THE MAIN FORECAST CHALLENGE AS ARCTIC AIR
SETTLES SOUTH AND WILL BE HARD TO ERODE. TODAY A LEE SIDE TROUGH
FORMS ALONG THE NORTHERN ROCKIES AND EXTENDS SOUTH BUT THE SPLIT
FLOW PATTERN WILL LIMIT THE SOUTHERN EXTENSION OF WARMER AIR.
ALONG AND EAST OF HIGHWAY 83 TEMPERATURES WILL START OUT WELL
BELOW ZERO WITH A TEMPERATURE RECOVERY TO MAX OUT IN THE 20S AS
EXTENSIVE SNOW COVER TEMPERS THE HEATING PROCESS IN THE NEAR TERM.
TONIGHT CLEAR SKIES AND LIGHT SOUTHWEST WINDS WILL AGAIN ALLOW
FOR GREAT RADIATIONAL COOLING TO BUST GUIDANCE LOWS FOR DAYBREAK
WEDNESDAY WITH READINGS UNDERCUT. WEDNESDAY A COLD FRONT WILL
MOVE SOUTHEAST DURING THE EVENING WITH MOISTURE LIMITED WITH THIS
SYSTEM AS IT MOVES SOUTHEAST...WITH DRY FORECAST CARRIED FORWARD.
THURSDAY THERE WILL BE A REINFORCING SHOT OF COLD AIR WITH
TEMPERATURES REMAINING BELOW NORMAL THROUGH THURSDAY.

.LONG TERM...(FRIDAY-SATURDAY) 
MODEL SPREAD DECREASING WITH UPPER RIDGE TO REBUILD OVER THE
NORTHEAST PACIFIC AS UPPER LOW DROPPING TO ACROSS THE SOUTHWEST.
THE TRACK OF THE UPPER LOW DOES REMAINS IN QUESTION WITH THE
POTENTIAL TO LIFT OUT SATURDAY THAT WILL BRING AN INCREASE IN
CLOUD COVERAGE. FOR NOW FEW CHANGES MADE AS LARGE UNCERTAINTY
REMAINS IN TRACK AND MOISTURE AVAILABLE.

&&

.AVIATION...ONLY A FEW HIGH CLOUDS EXPECTED WITH VFR CONDITIONS FOR
THE NEXT 24 HOURS.
