EARLY WEEK OUTLOOK
THE FIRST OF SEVERAL SHORTWAVE TROUGHS IS MOVING ACROSS THE AREA
THIS EVENING. SCATTERED TO WIDESPREAD SHOWERS HAVE DEVELOPED AS A
RESULT AND WILL CONTINUE INTO THE NIGHT. MOUNTAIN SNOWFALL IS
EXPECTED GENERALLY ABOVE 8-9 KFT SO THE PASSES COULD BECOME SNOW
COVERED THROUGH OUT THE MORNING. LINGERING MOISTURE WILL BE
SUFFICIENT FOR MORE PRECIPITATION ON MONDAY. A SUBTLE WAVE MAY CLIP
THE NORTHWEST CWA, SO THIS IS WHERE THE HIGHEST CHANCES WILL
BE. OUTSIDE OF THAT INSTABILITY AND OROGRAPHICS WILL BE
RESPONSIBLE FOR SHOWERS FOR THE REST OF THE AREA. THE FINAL
TROUGH MOVES OVER MONDAY NIGHT INTO TUESDAY MORNING. THIS WILL
KEEP PRECIPITATION CHANCES GOING MAINLY ALONG AND NORTH OF I-70.
MOUNTAIN SNOWFALL COULD AGAIN IMPACT THE ROADWAYS AT PASS LEVEL
MAINLY DURING THE OVERNIGHT HOURS. THE COVERAGE AND INTENSITY
OF SHOWERS DECREASES TUESDAY AFTERNOON AND THINGS SHUT DOWN IN
THE EVENING. WEDNESDAY WILL BE A FAIRLY QUIET DAY AND SLIGHTLY
WARMER GIVEN THE LACK OF SHOWERS. THE EXCEPTION WILL BE THE
NORTHERN DIVIDE WHERE LIGHT SHOWERS ARE POSSIBLE.
LATE WEEK OUTLOOK
DETERMINISTIC MODELS ARE CONTINUING TO SELL A BOWLING BALL LOW
WORKING ACROSS THE SOUTHWEST LATE THIS WEEK. ENSEMBLES ARE KEEPING A
RICH POOL OF MOISTURE TO OUR SOUTH. IT LOOKS LIKE WE GET SOME
BENEFITS OF THAT IN OUR SOUTHERN COUNTIES ON THURSDAY AND FRIDAY,
LIKELY WORKING UP THE DIVIDE TOO. TEMPERATURES AT THE MOMENT MAKE
THIS LOOK LIKE A NIGHT TIME SNOW PRODUCER FOR THE MOUNTAINS AND
LIKELY RAIN/SNOW MIX THROUGH THE DAY. MOISTURE DOES LOOK IMPRESSIVE
WITH THIS SYSTEM. THE TRACK OF THE LOW IS GOING TO HAVE SOME STRONG
INFLUENCE ON IMPACTS THOUGH. LOOKS LIKE A GOOD ONE TO KEEP AN EYE ON
IN THE COMING DAYS.
