Rain moves in then real cold headed our way
RAIN ARRIVES AND WILL HANG AROUND
Light rain showers pushed into western Indiana after sunset Wednesday and will continue to fill in across central and southern Indiana before sunrise. It is the start of a damp couple of days with occasional light rain and showers persisting through Friday evening. A continuous rain is not expected but a prolonged stretch could produce rainfall amounts of over three-quarters of an inch. The average of 7 different rain fall generating compute estimates .47” for the city with a range from .19” to .82”. Plan on wet weather for the next 4 commutes with the areal coverage on the rainfall reaching 88% Thursday and 80% Friday. Showers are forecast to then diminish from north to south Friday night
TEMPERATURE DROP – 2 COLD FRONTS COMING
There is real cold coming to central Indiana this weekend as it arrives starting Friday as the first of 2 cold fronts pass early in the day. Slightly milder air is arriving Thursday and into early Friday with a rise to around 50° but it is brief, the temperatures start falling Friday afternoon. As the first front moves through it will be bringing an end to the rainfall, the second front arrives Saturday as winds freshen up from the north. A few snow showers could accompany the front late Saturday afternoon or evening.
EARLY SEASON ARCTIC AIR
The cold is emerging tonight in the northern Plains where temperatures could drop to 10 degrees below zero by Thursday morning. A massive arctic high pressure (1050) will drop south and spread east through the weekend. The high pressure could be a record breaker for some states and is likely to be the highest here in a November since 2004! The air coming will be the coldest in 9 months and even more impressive will keep temperatures below freezing Sunday afternoon. We are currently forecasting a high of only 27° – that’s 21 degrees below normal and the coldest November afternoon in 13 years!
WITH COLD IN PLACE SMALL SNOW CHANCE
The heart of the cold retreats quickly Monday morning but on its heels a push of moisture could bring some light rain and snow into the state. No accumulation is expected, but hints of a bit of snow Monday night will need to be monitored in the coming days and its impact on Monday evening or Tuesday morning’s commutes. At this distance any snowfall would be very light.
We may be talking COLD turkey this Thanksgiving. Another push of cold air is in the forecast arriving next Wednesday into Thanksgiving day. The forecast at this distance for Thanksgiving looks sunny but cold with a high only in the 30s – 30 degrees colder than last years and possibly the coldest Turkey day since 2002 (36°).
