Scattered snow showers are departing late Wednesday afternoon. The snow showers come in the wake of a cold front that passed in the early morning hours. Snowfall amounts varied as these “downpours” of snow occasionally pass through. official snow tally came to just shy of a half-inch in the city but reached 1″ in some locations. Skies clear tonight and temperatures are sinking. Forecast low temperature could reach the upper teens away from the city.
A fast-moving low pressure system called a “clipper” (named after fast-moving ship of the 1800’s) will spread clouds into central Indiana early Thursday and eventually develop snow by early afternoon. A band of snow to perhaps 1″ accumulation possible from northwest to southeast before ending late Thursday evening. The track and available moisture is still being refined but current forecasts for snowfall off 6 machines suggest about a half inch of snow. Amounts range from nothing to 1.4″. A clearer picture will be available later tonight.
COLD ST. PATTY’S DAY
Last year St. Patricks’ day reached 77°, the warmest ever and continued a 4 year stretch of warm and sunny St. Patty’s days. The streak ends this weekend. In fact, early thinking is that this year will be 35 to 40 degrees colder than last.
There is growing evidence that Sunday could be a wintry mess but it is far from a definite conclusion. Various computer forecasts hint at a stalled front over southern Indiana with a large cold high pressure north of the state. Teh set-up looks favorable for a cold rain, wet snow or even freezing rain scenario but still unclear. be sure to check back through the week as this system unfolds. The trusted European long-range forecast model hints at appreciable e snow while U.S. forecast models hint at a glancing blow to nothing but rain. More in the days ahead.
COLD PATTERN NEXT 2 WEEKS
With the exception of Friday ( temperatures are expected to rise into the lower 50’s late in the day) the overall pattern is cold. A four-week stretch of chilly weather will roll on perhaps through the end of the month. Since mid February, a blocking pattern has developed over the North Atlantic. This block creates a buckle in the jet stream and allows cold air to set up shop for extended periods over the eastern half of the nation. While a temporary warm up (a couple of days) is possible the overall view is chilly. here is a break out of high temperatures over the next 16 days.
PAST 5 DAYS: +4°
DAYS 1-5: -11°
DAYS 6-10: -12°
DAYS 11-16: -12°
The average high temperate over the next 2 weeks rises from 51° to 55°
