Good late afternoon bloggers,
Heavy bands of snow are forming and by the time we are into our 5 and 6 PM newscasts I will be able to pick out the most likely spots for the heaviest snow. We just expanded the area on our latest snowfall forecast. Lawrence just went down to 1/4 mile visibility in heavy snow and this is moving into the city. Here is the latest forecast:
Here is the meso-discussion from the Storm Prediction Center. How often do you see this for Kansas City…..NEVER!
BANDS OF HEAVY SNOWFALL WILL INTENSIFY ACROSS NERN KS AND NWRN MO
THIS AFTERNOON INTO EARLY EVENING…WITH RATES OF 1 TO LOCALLY 2
INCHES PER HOUR EXPECTED. THE HEAVY SNOW WILL IMPACT THE KANSAS CITY
METRO AREA BY 00Z.
STRONG DEEP-LAYER ASCENT CONTINUES TO OVERSPREAD THE CENTRAL PLAINS
AHEAD OF A VIGOROUS SHORTWAVE TROUGH DIVING SEWD ACROSS THE WRN
CONUS. A LLJ AHEAD OF THE TROUGH IS CONTRIBUTING TO ISENTROPIC
UPGLIDE ATOP THE COLD AIR MASS ENVELOPING THE NORTHERN PLAINS AND
UPPER MIDWEST. CONVERGENCE IN THE EXIT REGION OF THIS LLJ…ALONG
WITH ISENTROPIC UPGLIDE AND INCREASING LARGE-SCALE ASCENT…WILL
RESULT IN INCREASING SNOWFALL RATES ACROSS THE DISCUSSION AREA THIS
ADDITIONALLY…INCREASING LOW/MID-LEVEL FRONTOGENESIS IS EXPECTED TO
OCCUR INVOF THE INTERSTATE 70 CORRIDOR BY EARLY EVENING AIDED BY
850-MB DEFORMATION. THIS WILL FAVOR THE DEVELOPMENT OF SNOW
BANDING…ESPECIALLY ACROSS THE KANSAS CITY METRO AREA…WHERE
MODELS INDICATE THE DEVELOPMENT OF SLANTWISE INSTABILITY LATER THIS
AFTERNOON. WITH FORECAST SOUNDINGS INDICATING STRONG ASCENT THROUGH
A SATURATED DENDRITIC GROWTH ZONE…EFFICIENT SNOW GROWTH IS
ANTICIPATED…WITH RATES EXPECTED TO REACH 1 TO LOCALLY 2 INCHES PER
HOUR IN THE SNOW BANDS.
Let us know what you are experiencing. We will update the blog after the 6 PM newscast.
