AFTERNOON – OVENRIGHT: The cold front that brought rain and t’storms to the forecast zones last night has since moved off to the east of the region. As it did the precipitation and most of the clouds went with it, as we have started the day off sunny to mostly sunny across the forecast zones.
Today the main weather feature will be an upper level trough and piece of upper level energy that will be moving across the forecast area. This will help generate more clouds and some isolated to widely scattered rain showers today.
A couple isolated showers are currently ongoing across very northwestern zone 1. However, as we progress through the day more widespread showers will become likely. By 2-3 PM you can see those showers per the latest HRRR model. While showers do look more likely from Indianapolis north, more isolated chances will exist across southern zone 1 and zone 6 as well.
While rain shower chances will persist through the evening, once we head into the night-time hours and lose the daytime heating, they will start to fade out. By 10 PM only a few isolated showers look to be left across Indiana.
Any accumulation from these showers will be on the low side. Up across northern zone 1 .10-.30” or so can’t be ruled out. However, most places will see far less rainfall.
Overnight showers will end and clouds will fade out once again. Lows will be chilly bottoming out in the low 30’s north to near 40 south.
WEEKEND: An upper trough will remain in place on Saturday. Another upper level vorticity maximum will move to the southeast across northern Indiana and into Ohio through the day.
While this won’t cause any major issues, it will spark more isolated to scattered rain showers across the forecast area.
By 12-1 PM Saturday afternoon some rain chances will become possible across northern zone 1 as the piece of energy moves through.
Through the afternoon scattered areas of rain will remain possible across both zones 1 and 5. However, better chances will likely lie closer to the vort. max across eastern Indiana and into Ohio. By 5 PM the models do pick up on that better chance of rain across those areas.
New rainfall Saturday looks to be around .10-.20” with some isolated areas closer to the vorticity max. possibly seeing up to .40”. Regardless, I’m not expecting any real soaking rains.
Highs on Saturday will be in the mid 40’s north to around 60 south.
Winds may end up being the biggest story on Saturday. Very strong winds will be in place across the region with gusts of 40-50 mph possible!
Temperatures in afternoon into the overnight will drop pretty quickly. Lows overnight will be below freezing in some spots. Lows will drop into the mid 20’s north to mid 30’s south.
I will mention, if a little moisture can stick around late evening into the early overnight I won’t rule out a few snowflakes. However, they will be just that…few. No accumulation is expected.
Sunday will be the nicest day of the weekend. This will be as an area of high pressure ridges in from the south ahead of a developing area of low pressure to the northwest.
With the high in place it will cause the trough to retreat northward some. This will setup for a sunny and warmer end to the weekend.
Highs on Sunday will be in the low 50’s east to around 60 west. Winds will remain breezy at times on Sunday with gusts of 25-30 mph possible.
MONDAY: The area of low pressure to our northwest on Sunday will move to the southeast. As it does it will bring a cold front through the forecast area very late Sunday night through Monday.
Along the front isolated to perhaps scattered rain could develop and impact zones 1 and 5 on Monday. Right now models are not overly impressed with rain chances. The EURO only has isolated showers, while the NAM/GFS has almost no precipitation.
For now, we will call for isolated showers or a storm possible (10-20% chance). However, I won’t be surprised if models dry the precipitation up over the next several runs.
Highs on Monday will be dependent on where the cold front is located. Places where the cold front moves through early will only see highs in the low to mid 50’s. However, farther south where the cold front doesn’t move through until late afternoon/evening highs will warm into the mid to upper 60’s.
Winds on Monday will remain strong with gusts of 20-30 mph possible.
MID TO LATE NEXT WEEK: Tuesday looks to be mostly dry, but better rain chances look to come in late Tuesday and Wednesday with a larger storm system.
Behind that an upper-level trough will build into the forecast region by late next week. This will bring in much cooler weather along with more unsettled weather.
Temperatures to start April look to be much below average.
