Saturday Forecast: Chilly Weekend; Eyeing Another Significant Storm…

Updated 11.01.13 @ 10:53p

Zionsville, IN After a day filled with heavy rain and damaging winds, we closed the week out with chilly, but pleasant weather conditions.  We’ll enjoy a chilly weekend ahead and we’re eyeing another significant storm system that promises to have a renewed threat of heavy rain, severe weather, and a big temperature drop next week.

Status-weather-showers-day-iconSaturday: Mostly cloudy; Passing shower (0.05) 42/ 50

Reinforcing chilly air will blow into the state Saturday.  This will be accompanied by mostly cloudy skies, blustery northwest winds, and the threat of a passing light shower or sprinkles.  Grab the coat or jacket before heading out to get those Christmas lights put up or take care of those outdoor chores.

Status-weather-clouds-iconSunday: Partly cloudy; 33/ 51

We’ll wrap up the weekend with dry and chilly weather.  Plenty of sunshine will team up with cool, crisp fall air to present a beautiful close to the weekend.

 

Status-weather-clouds-iconMonday: Partly cloudy; 35/ 57

Partly cloudy skies and seasonable temperatures will greet folks on the way back to school and work.

 

Status-weather-showers-day-iconTuesday: Increasing clouds; developing nighttime showers (0.10) 48/ 60

We’ll eye our next storm system for a mid week arrival. Tuesday should start sunny, but mid and high level cloudiness will be on the increase followed by developing nighttime showers as warmer, more muggy, air moves over the top of the dry, chilly air in place initially.

Status-weather-showers-day-iconWednesday: Scattered daytime showers, increasing at night with thunderstorms (0.60)  54/ 62

A cold front will slide through the region Wednesday night and Thursday morning and this will be the focal point of more widespread showers and thunderstorms. We stress that it likely won’t rain all day Wednesday, but showers will be possible before the more widespread rain and thunderstorms Wednesday night into Thursday.

We’re monitoring this storm for a renewed threat of heavy rain and severe weather. At this distance, it’s far too early to be precise with the threat details, but we think widespread 1″+ rains are likely along with another enhanced straight-line wind event for at least portions of central Indiana during the Wednesday night/ Thursday time period.  Each storm system is different and presents its own set of challenges, but this storm has a few similarities to that which we just dealt with.

We have time to watch things and we’ll update accordingly as we move forward.  Stay tuned.

Status-weather-storm-night-iconThursday: AM Thunderstorms (0.50″) 42/ 55

We forecast thunderstorms to be likely Thursday morning, but as the cold front slides east of the region, the rain chance will end from west to east through the day.  Temperatures will cool dramatically as we go through the afternoon and evening hours with falling temperatures after a midnight high.

Status-weather-clouds-iconFriday: Partly cloudy; 32/ 45

The big story as we wrap up next week will be the colder air.  In fact, latest model data suggests we plunge into the 20s for lows by next Saturday morning.

Wednesday Forecast: Getting To Be That Time Of Year!

Updated 10.15.13 @ 4:42p

Zionsville, IN Rain showers will continue pushing east of the region tonight and we should be rain-free Wednesday. We discuss what’s sure to be a busy, chilly forecast below!

Status-weather-clouds-iconWednesday: Partly cloudy; 50/ 61

Tuesday’s rain will be all, but a memory Wednesday with sunshine returning to your forecast. A north breeze will be in play, helping usher in cooler temperatures.

 

Status-weather-showers-day-iconThursday: Scattered showers; 0.10; 44/ 58

Some weak upper level energy will move across the state on Thursday and this could help spark a scattered shower.  We’re not looking at all day rains or significant rainfall by any means.  Besides the rain, the other big weather story Thursday will be the chilly air.  We’ll be far below the middle 60s, which is considered the normal high for this time of year.

Status-weather-clouds-iconFriday: Partly cloudy; 42/ 63

We’ll wrap up the work week with very pleasant autumn weather.  A secondary cold front and resurgent chilly air will be set to invade for the weekend, but we think the frontal passage holds off until Friday night. As of now, we forecast the front to come through dry.

Status-weather-clouds-iconSaturday: Partly cloudy; 40/ 54

Cool Canadian air will flow into the Hoosier state Saturday amidst chilly northerly breezes.  Winds may gust upwards of 20 MPH or so during the daytime Saturday.  You’ll certainly need that jacket or sweater as you head out to the fall festivals or the pumpkin patch!

Status-weather-clouds-iconSunday: Partly cloudy; 38/ 57

Weather conditions will be very similar to that of Saturday on Sunday.  Dry skies and chilly breezes will dominate our landscape.  Temperatures will remain below average.

 

Status-weather-showers-day-iconMonday: PM shower chance; 0.10; 39/ 64

Our winds will back around briefly to the southwest and allow just enough moisture northward to potentially lead to a broken band of showers to move through the region Monday evening/ early Tuesday ahead of our next cold front. Most of your daytime Monday will remain dry and rain-free.  This front is packing a punch in the temperature department and will likely produce the coldest air so far this fall season by the middle of next week, including the chance of the first official freeze for IND.

imagesTuesday: Mostly cloudy; 41/ 49

As of now, next Tuesday is shaping up to be a rather cloudy, raw day.  Strong cold air advection will be ongoing.  Gusty north winds will help usher in the coldest air so far this fall season.  In fact, highs likely will remain below 50 degrees next Tuesday with mostly cloudy skies and chilly north winds.

Friday Forecast: Busier Times Ahead In The Good Ole Forecast Office!

Updated 10.11.13 @ 6:45a

Zionsville, IN I, like many of you, make sure to enjoy the last of the warm, sunny weather this time of year.  As veteran Hoosiers know, the months ahead present a cloudy, bitterly cold, and windy time of things.  Thankfully, we have another gorgeous day lined up to close the work week.  We discuss this and busier times ahead below!

Status-weather-clouds-iconFriday: Partly cloudy; 48/ 76

It’s only fitting that we close out the work week with the same type of weather we’ve enjoyed all week long- a cool start followed by beautiful weather conditions through the afternoon.  Get outside and spend some time soaking up the sunshine!

Status-weather-showers-day-iconSaturday: Mostly cloudy; scattered evening/ nighttime shower; 0.10″ or less; 50/ 76

Most of your daytime Saturday will provide pleasant weather to get some of those last minute chores taken care of.  We’ll notice an increase in our cloud cover followed by a broken line of showers (perhaps a rumble of thunder) rolling through the state from west to east.  We’re not looking at significant rainfall with this system.  In fact, we think most communities pick up less than one tenth of an inch of rain (if that).

Status-weather-clouds-iconSunday: Partly cloudy; 55/ 70 

While some of our extreme eastern counties may see an AM shower Sunday, most of the day will be rain-free and feature increasing sunshine.  It’ll be another pleasant day for outdoor activities.

 

Status-weather-clouds-iconMonday:  Partly cloudy; 45/ 69

High pressure and an associated northerly air flow will dominate our weather to begin the new work week. North breezes may gust upwards of 15 MPH Monday and this will help keep us cooler than the weekend. We’ll start the day quite chilly (middle 40s for most) before warming into the upper 60s.

Status-weather-showers-day-iconTuesday: Increasing cloudiness, PM shower; 0.10″; 54/ 73

While we have some timing issues to work out as we draw closer to the event (GFS is more progressive whereas the ECMWF is slower), we’ll go ahead and introduce shower chances to your forecast as early as Tuesday evening. Stay tuned as we fine tune things.

Status-weather-showers-scattered-iconWednesday: Rain; 0.50″; 49/ 64

As of now, we see a cold front moving through the region Wednesday. Ahead of the front, showers and possibly a thunderstorm will blow through the region.  Our winds will shift to the northwest Wednesday night/ Thursday, helping drive the coldest air so far this season into the Hoosier state Wednesday night and Thursday.

Status-weather-showers-scattered-iconThursday:  Rain; 0.50″; 44/ 57

Again, as we posted above, timing is everything with our mid to late week cold front.  Overnight model data places a heavier corridor of rain through central Indiana mid week- potentially as much as 1″-1.25″ over the two day period.

We also want to continue pointing out that with the PNA shifting back into the  positive, the stage is set for chilly air to hang around the region with more “staying power” as we move through October’s second half.  We’ve covered this in posts below and will continue to go over things as we move forward…  It’s time to certainly pull out those coats! 🙂
