Forecast Discussion

AFTERNOON – OVERNIGHT: A strong 1030 mb area of high pressure continues to sit across the Gulf Coast region along the TX/LA line today. This area of high pressure will remain in control of our weather to start the week as the northerly extent ridges into the region.

NOW

Through the afternoon and evening sunny to mostly sunny skies will be in place with only some high clouds working into zones 1 and 5.

Through the overnight conditions will remain calm with mostly clear skies. Lows tonight will fall into the low 30’s north to upper 30’s south.

TUESDAY: Overnight Monday into Tuesday the area of high pressure will move off to the east. As it does an area of low pressure will start to develop off the eastern Rockies and western Great Plains region. This will allow our winds to shift out of a more southerly direction for Tuesday.

TUE

Highs on Tuesday will be warmer with temperatures topping out around 60 north to the upper 60’s south. Winds on Tuesday will be strong at times, with gusts of 25-35 mph.

TUESPAN

I think most of the day on Tuesday will be mostly sunny to partly cloudy. However, by late in the day towards sunset some clouds may start to work in from west to east across zones 1 and 5.

Tuesday night into Wednesday morning clouds will start to thicken up as the area of low pressure moves closer to the forecast region and a warm front remains in place to the north. While precipitation chances will be very low, a stray shower is not out of the question through the overnight.

WEDNESDAY: The area of low pressure and cold front will be to the forecast zones west and northwest through the daytime hours on Wednesday. To the north the residual warm front will be in place, so we will remain in the warm sector of this storm for Wednesday.

WFWED

Highs on Wednesday will be in the low 60’s north to upper 60’s south. It does look like we will be mostly cloudy to completely overcast across zones 1 and 5 on Wednesday. However, if we should see some sunshine break through it wouldn’t take much to spike temperatures a little higher.

WEDPAN

Through the day on Wednesday a few isolated areas of afternoon rain will be possible. However, most areas look to remain dry. If you do see one of those isolated showers it will be pretty short-lived with no heavy rainfall expected.

WED2PM

Winds on Wednesday will remain strong at times with gusts up to 35 mph possible.

Wednesday night a cold front will start to approach the forecast zones from the west. Rain and some t’storms will develop along and perhaps just ahead of the front. Scattered rain and storms look to enter western Indiana around 3-5 AM Thursday.

THU2AM

The cold front will enter western Indiana around 7-9 AM Thursday morning along with scattered rain and t’storms.

THU8AM

By 11 AM – 12 PM Thursday the cold front will be moving across central Indiana and into the Indianapolis area. Along this front rain and t’storms will be possible, these will be moving off to the east through the afternoon.

THU11M

Thursday afternoon into the evening the rain and storms will move off to the east of the forecast region. Likely exiting the zones entirely by 7-8 PM.

Highs on Thursday will come early before the cold front passage. Highs will be in the lower 50’s west to around 60 east where the front passes later. Winds on Thursday will be very strong with gusts of 40 mph or so possible!

winds

THUPAN

Behind the front cold air will quickly surge in and temperatures will tumble throughout the day. As they do, any precipitation left over Thursday evening into the overnight could change over to some snow showers. However, no accumulation is expected.

THU7PM

Thursday night lows will fall into the upper 20’s to mid 30’s across zones 1 and 5.

FRIDAY: An area of high pressure will build in late Thursday night through Friday. This will allow clouds to decrease from west to east, giving us some sunshine to end the week.

FRI

However, temperatures will remain cool with highs only in the mid 40’s north to mid 50’s south.
