Some sun today, showers Wednesday, winter cold returns next week
Less cloud cover and wind shift to the southeast are doing the temperature trick today. Central Indiana is a good 15 to 20 degrees warmer than this time 24hrs ago, and we should continue to climb well into the 50s.
High resolution visible satellite imagery at 1pm shows a slowly dissipating stratus cloud deck across the southern-third of the state. Expect a rapid rise in temperatures as the overcast thins, and highs will range from 55 to near 60 degrees.
Due to seasonably mild highs, dry conditions and partly to mostly conditions we believe today will be one of our better weather set-ups over the next 7 to 10 days. Though Friday will be warmer, there are rain chances early and late. Speaking of rain…we're still expecting an arrival of showers and embedded thunder after 12am tonight and prior to 6am Wednesday. So the morning commute could be soggy and will definitely be windy with gusts possibly over 30mph as strengthening low pressure treks across the Great Lakes.
The combination of cloud cover and the passage of cold front in the morning will keep temperatures steady in the middle to upper 40s. Rain amounts by 4pm tomorrow will range from a tenth to a quarter of an inch.
The spring equinox (when the sun crosses over the plane of the equator into the northern hemisphere) occurs at 12:57pm Thursday, and highs Friday will certainly be spring-like in the middle to upper 60s. But this will be an exception and not rule of the medium to long range pattern
There is significant model agreement in a cross-polar flow developing to finish the month of March. The end result will be below to much below normal temperatures, and quite a winter chill next week. Highs Sunday into Wednesday will likely be in the 30s…some 15 to 25 degrees below normal. This pattern will also promote snow possibilities across the Great Lakes and Ohio Valley, though it's much too early to speculate on whether or not accumulation can be expected. At the very least don't bother packing away the winter gear. Layers will be needed next week for sure! Have a great afternoon and thanks for visiting the blog – Sean Ash
