Weak closed low in central Oklahoma at midday, with associated weak deformation zone continuing to spread cirrus into southern Kansas. Winds back more SE this afternoon, with decreasing cirrus and highs in the low to mid 70s. Windy and warmer. Powerful cyclone spinning over the NE Pacific this afternoon. Models are in excellent agreement, and displaying impressive consistency, regarding this cyclone's track as a strong omega block forms over North America this weekend.
THIS ENCLOSED LOW WILL PRODUCE BROAD SYNOPTIC ASCENT ALONG AND BEHIND THE COLD FRONT. THE OTHER INTERESTING FEATURE OF THIS SYSTEM IS HOW COLD THE AIR MASS IS BEHIND THE COLD FRONT. AS FOR SNOW, WE'RE EXPECTING RATHER LOW SNOW LEVELS, BUT WILL HAVE TROUBLE ACCUMULATING AT SOME OF THE LOWER ELEVATIONS. AFTER THIS SYSTEM PASSES, HIGH PRESSURE WILL SETTLE IN.
HIGH PRESSURE WILL BUILD IN FROM THE NORTH OVER THE AREA FOR THE NEXT SEVERAL DAYS. THE RIDGE WILL SHIFT EASTWARD OVER THE MID ATLANTIC. LOWS MAINLY IN THE LOW 40S. AND UPPER LEVEL LOW MEANDERING OVER THE GULF COAST STATES COULD ADVECT IN ENOUGH MOISTURE ALOFT TO GENERATE SOME CLOUDS.
A BIT MORE DRYING/CLEARING TOMORROW WITH THE UP- PER RIDGE BUILDING IN FROM THE WEST. ISOLATED SHOWERS WILL REMAIN POSSIBLE THROUGH THE OVERNIGHT PERIOD AS SMALLER DISTURBANCES ROTATE ACROSS THE REGION ASSOCIATED WITH AN UPPER LOW OVER OKLAHOMA SLOWLY MOVING EAST.
