AFTERNOON – OVERNIGHT: We have started the day with clear skies across zones 1 and 5. This is thanks to an area of high pressure that is in place across the region, but is making its way off to the northeast.
Through the afternoon into the evening most of the area will remain sunny to mostly sunny. However, across zone 5, especially the southern half, clouds will start to build in ahead of an approaching upper-level low.
Through the overnight clouds will continue to move in across zone 5 and possibly southern portions of zone 1. Precipitation chances will be very minimal with only a few sprinkles or a very light shower across southern zone 5 late in the overnight.
Lows overnight will fall into the mid 30’s north to mid 40’s south.
THURSDAY: An upper-level area of low pressure will be cut-off from the main jet stream(s) on Thursday. This will cause the low to spin to the regions south.
With the low in place clouds will be on the increase across the southern half of Indiana through the day. By 6-8 AM some isolated, light rain showers will be possible across zone 5 and they move to the northwest and west around the upper-level low.
Through the morning hours and into mid-day isolated rain showers and sprinkles will remain possible across zone 5, especially closer to the Ohio river in southern Indiana.
Through the afternoon and into the evening a few isolated showers may persist across zone 5. However, I think rain chances look pretty minimal through the afternoon and evening, with most places remaining dry.
Highs on Thursday will be in the upper 50’s north to near 70 south.
Thursday night dry conditions will be in place. However, partly cloudy conditions will persist across zones 1 and 5 Thursday night.
Lows Thursday night into Friday will be in the upper 30’s north to upper 40’s south.
FRIDAY: The upper-level low will start to weaken Thursday night and through the day on Friday. As it does the impacts on our weather will be far less Friday than what they will be Thursday. Especially as the jet stream picks up the low and exits it out of the region.
Friday will be a very nice day with a mix of sun and some clouds around. However, it will be mostly dry with only a very isolated shower possible in the afternoon across Indiana.
Highs on Friday will be in the upper 60’s north to mid 70’s south.
SATURDAY: A very nice weekend looks to be in store across the forecast area. As the upper-level low moves out of the region it will allow for the high pressure ridge to expand over the eastern U.S.
This will allow for sunny to mostly sunny skies with highs in the upper 60’s to mid 70’s to overspread the region Saturday!
SUNDAY: The upper-level ridge will continue to build in across the eastern U.S. on Sunday.
As it does, the area of high pressure at the surface to the east will ease its way back to the west. With two areas of high pressure influencing our weather, I expect sunny to mostly sunny skies on Sunday with only a few high clouds working in.
Highs on Sunday will be around 70 north to perhaps the upper 70’s south!
LONG RANGE (NEXT WEEK): The upper-level ridge will start to break down on Monday as a trough pushes southward across the northeastern U.S.
By Monday evening a frontal boundary will be moving southward across the region. This will allow for some rain showers and perhaps a few storms to develop and move across the area through the late afternoon/evening.
Through mid next week high pressure looks to be in control. This before a better organized system moves into the region late next Wednesday into Thursday. That will be our best chance at rain over the next 7 days.
Temperatures may briefly cool off next week as the trough moves in. However, the overall forecast will still call for temperatures to be around average.
