SASKATCHEWAN EARLY THIS MORNING. THIS IS THE FOCUS FOR
LIGHT...SCATTERED SNOW THIS MORNING. RADAR SHOWS VERY LIGHT SNOW
ENTERING NORTHWEST NORTH DAKOTA. AS THE TROUGH PUSHES OFF TO THE

MORNING AND DIMINISH. A SECONDARY AREA OF PERHAPS MORE WIDESPREAD
LIGHT SNOW IS EXPECTED TO DEVELOP LATER TODAY AS AN UPPER LEVEL
SHORTWAVE TROUGH MOVES THROUGH THE SOUTHERN CANADIAN PRAIRIES AND
SWINGS THROUGH NORTHEAST NORTH DAKOTA. THE SHORT TERM HIGH-RES
MODELS AND THE GLOBAL MODELS ALL INDICATE A LIGHT BAND OF SNOW

MAIN CONCERNS IN THE EXTENDED ARE STRONG WINDS AND SOME LIGHT

EXISTS ON THE STRENGTH OF THE WINDS.

REGION WITH REINFORCING COOLER AIR ACROSS THE NORTH AND SOME
RESIDUAL LIGHT SNOW ACROSS THE SOUTHEAST THURSDAY MORNING. A WARMUP
WILL BEGIN ON FRIDAY AS AN H500 RIDGE GETS NUDGED INLAND BY STRONG

A CHINOOK FLOW WILL BRING MILDER AIR ON SATURDAY WITH THE PASSAGE
OF ANOTHER SHORTWAVE.

THIS MORE SIGNIFICANT SHORTWAVE WILL TRACK ACROSS THE PLAINS ON
SATURDAY NIGHT AND SUNDAY. PAST MODELS RUNS FOCUSED THE STRONGEST
H850 WINDS ACROSS THE SOUTHWEST. LATEST 00Z MODELS BRING WINDS
MORE BROADLY ACROSS THE STATE WITH SURFACE PRESSURE RISES FOCUSED
IN SASKATCHEWAN AND MANITOBA. THIS INTRODUCES MORE UNCERTAINTY IN
