TUESDAYS MORNING COMMUTE |
ANOTHER ROUND OF WINTRY WEATHER IS EXPECTED TO DEVELOP LATE TONIGHT INTO WEDNESDAY. A STRONG PACIFIC JET WILL DIG FURTHER AND CONTINUE TO SUPPORT A NEGATIVELY TILTED TROUGH. A SWATH OF STRONG FRONTOGENESIS WILL OCCUR SOMEWHERE ACROSS NORTHERN UTAH WHICH WILL LIKELY SUPPORT A BAND OF HEAVY SNOW. VERTICAL MOTION THROUGH THE DENDRITIC SNOW GROWTH LAYER WILL SUPPORT LARGE DENDRITES AND SIGNIFICANT SNOW RATES. THE QUESTION IS WHERE WILL THIS BAND DEVELOP? CURRENT MODELS IN GOOD AGREEMENT THAT IT WILL DEVELOP BETWEEN WENDOVER...THE WASATCH FRONT AND EVANSTON. THIS COULD AND LIKELY WILL SHIFT SOME. BUT WHEREVER THE BAND DEVELOPS...SIGNIFICANT IMPACTS ARE EXPECTED. DEFINITELY CHECK LATER FORECASTS AS THE WEDNESDAY MORNING COMMUTE COULD BE SIGNIFICANTLY IMPACTED. ALSO DURING THIS TIME...THE SURGE IN COLDER AIR FROM NORTH TO SOUTH COULD SUPPORT A LEGITIMATE LAKE EFFECT SNOW BAND EXTENDING FROM THE GREAT SALT LAKE INTO THE TOOELE VALLEY AND WESTERN SALT LAKE VALLEY. ANOTHER RELATIVE BREAK IS EXPECTED WEDNESDAY AFTERNOON AND EVENING AS THE NOSE OF THE JET PASSES THE REGION AND THE AFOREMENTIONED PROCESSES DECAY. SHORT RANGE ENSEMBLES INDICATE WIDESPREAD AFTERNOON INSTABILITY SO MENTIONED THUNDER AGAIN WEDNESDAY AFTERNOON. THE THIRD ROUND OF WINTRY PRECIPITATION IS EXPECTED THURSDAY. WARM ADVECTION IN THE MIDDLE ATMOSPHERE SHOULD SUPPORT A BAND OF PRECIPITATION FROM SOUTHWEST TO NORTHEAST ACROSS MUCH OF NORTHERN AND CENTRAL UTAH. TRAJECTORIES OFF THE GREAT SALT LAKE SUPPORT THE THREAT OF LAKE EFFECT SNOW INTO THE SALT LAKE VALLEY AGAIN THURSDAY MORNING. ENJOY
