Tracking A Couple Of Cold Fronts This Week…

Highlights:

  • Calm open to the work week
  • Two cold fronts impact the region
  • Much colder air blows in this weekend

Calm Open; Busy Close…The work week will open with weak high pressure in control of our weather.  This will result in sunshine returning along with unseasonably chilly conditions (average highs are in the mid 50s this time of year).

The first of two cold fronts will push through the state Wednesday.  Clouds will increase Tuesday evening and showers will blow into town Wednesday morning.  Breezy and chilly conditions will go along with the damp weather.

A second (stronger) cold front will impact the area to close the work week.  Strengthening low pressure will move through the Great Lakes Friday evening and help pull a briefly warmer air mass into the state.  Showers and thunderstorms will be widespread ahead of the approaching cold front and a few of these could be strong to severe.  We’ll keep a close eye on things over the next couple of days and update accordingly.  Strong and gusty southwesterly winds will reach 40 MPH+ before shifting around to the northwest once the trailing cold front sweeps through the region.  This will drive a sharply colder air mass southeast and the potential is there for lingering moisture to end as a touch of wet snow late Friday night.  The weekend will feature dry, windy, and unseasonably cold conditions.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall:  Trace
  • Rainfall: 1.00″ – 1.50″

Severe Weather Sunday; Much Colder Next Week…

Highlights:

  • Clouds more bark than bite today
  • Stormy setup Sunday
  • Trending colder next week

All Eyes On Sunday…The cold front that passed through the region Thursday night and setup the gorgeous close to the work week is lifting back north this morning as a warm front.  This will result in overcast conditions today, areas of sprinkles or drizzle later in the day, and rising nighttime temperatures.  Scattered thunderstorms will develop across central Indiana late tonight with a warmer and increasingly moist environment.

Sunday will certainly be a day to remain weather-aware.  The overall setup hasn’t changed from what was discussed yesterday with a warm and moist southwesterly air flow in place ahead of an approaching cold front and associated area of low pressure.  Additional ingredients in play suggest we need to monitor the threat of large hail, damaging straight line winds, and potentially tornadoes.  Individual storms (potential super cells) are expected to fire across central and northern portions of the state Sunday afternoon into early evening.  These will be capable of quickly pulsing to severe levels and include potential of large hail, as well as tornadoes (particularly in the vicinity of the warm front which is expected to be draped across north-central parts of the state).  Individual cells are anticipated to “morph” into a squall line Sunday evening, including potential of a quick spin-up tornado, as well as damaging straight line winds.  With a moisture-rich air mass in place (precipitable water values are expected to approach 2″ Sunday evening), locally heavy rainfall is also expected.

All of our “excitement” will come to an end overnight Sunday and we’ll trend much colder (and calmer) during the new work week ahead.  Our next storm system will pass by to our south Tuesday, but may be close enough to spark a light shower across central portions of the state.  Drier and colder conditions build in later in the week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″ – 2.50″

Growing Severe Threat Sunday…

We have growing concerns of a severe weather event Sunday afternoon and evening across the state.  This morning, the Storm Prediction Center (SPC) has included most of Indiana in an “Enhanced” risk of severe weather.  From this distance, all modes of severe weather seem possible, including large hail, damaging winds, and even a tornado or two.

A trough and associated cold front will slice into an unseasonably warm and increasingly moist air mass Sunday.  Ahead of the approaching front, temperatures should climb into the lower 70s Sunday afternoon (average high is in the upper 50s) and dew points will reach the lower to middle 60s.  While the developing surface low isn’t expected to be terribly strong, as this feature moves northeast, it’ll help drag a cold front into this warm and increasingly unstable air mass late Sunday.  From this distance, conditions seem favorable for a couple of super cells to develop Sunday afternoon and evening.  We’ll have to keep a close eye on the northward extent of the warm front as this would be the areas of greatest concern for potential tornadic activity Sunday afternoon.  Large hail and damaging winds are also included in Sunday’s severe threat.  We’re in the second severe weather season, after all, and this kind of event isn’t unusual.  Late November 2013 comes to mind.

It’ll be important to remain weather-aware Sunday and stay tuned all weekend for future updates.  We’ll transition to a much cooler regime (back to below average) next week.

A cold front will slice into unseasonably warm and moist air Sunday afternoon and evening. A severe weather episode is a growing concern. Remain weather-aware.

A Cold Halloween On Tap…

Highlights:

  • Cold and blustery Halloween
  • Unsettled, milder weather builds in
  • Stronger cold front arrives early next week

Spooky Winds…Northerly breezes are strong and gusty and leading to wind chills in the lower-middle 20s across central Indiana this morning.  Heavier winter coats will be a smart choice out the door!  Otherwise, we’re a state divided from a cloud perspective: the southern half of Indiana will get in on the sunny act much sooner than the northern half of the state.  As we look towards the all-important trick-or-treat weather tonight, anticipate dry conditions, lighter winds, and unseasonably chilly conditions continuing.

Our next storm system will approach Wednesday with showers.  Rain may be mixed with wet snow or sleet Wednesday morning, but with temperatures above freezing, don’t look for any accumulation.  Periods of showers and light rain will continue Thursday into Friday morning.  Heavy rain won’t occur, but it’ll be damp at times.  Saturday is a bit tricky- some solutions keep rain around, but we’re choosing the more “optimistic” approach for the purpose of this forecast update.  Stay tuned.

Saturday will feature considerable cloudiness, slightly cooler air, and breezy conditions before a warmer close to the weekend.  A southwesterly flow will help boost highs into the upper 60s Sunday afternoon ahead of an approaching cold front.  That cold front will slide through here with showers and a couple claps of thunder Monday.  Much colder air returns Monday night into Tuesday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Trace
  • Rainfall: 0.50″ – 1.00″
