Wednesday Morning Notebook: Thursday Storm Threat; Heavy Rain Next Week…

I. Scattered light showers will impact the southern half of the state today, but these won’t be a big deal and more of just a nuisance for our Valentine’s Day.  Temperatures will remain in the 40s for most of the afternoon before rising overnight.

Forecast radar today at 3p shows scattered light showers around.

II. A cold front will drop in Thursday evening and this will deliver more widespread heavier rainfall and even a couple of thunderstorms Thursday night.  In general, we expect 0.50″ to 1″ of rain to fall.

III. We’ll turn briefly colder to close the work week. A couple of light snow showers are possible Friday morning and a wave of low pressure will “try” to push moisture into the cold air Saturday.  As of now, we remain unimpressed with the prospect of impactful wintry weather Saturday, but have included the potential of wet snow in our Saturday forecast.  Precipitation appears to be very light.  Nonetheless, we’ll continue to keep an eye on things.

IV. The pattern continues to scream and warm and wet next week as a big ole southeast ridge remains in place.  This will direct the steering current into the TN and OH Valley regions and multiple waves of rain, occasionally heavy, will result beginning early next week and continuing into the middle and latter portions of the week.  Widespread 2″ to 3″ totals with locally heavier amounts seems to be a good bet next week.

We note a true Gulf connection and precipitable water values that will exceed 300% of normal at times.  Parts of the Ohio Valley will deal with flooding, but it’s premature to get more specific than that from this distance.  If you live near waterways, plan to keep a close eye on future updates and forecasts.

V. We note data continues to suggest a colder period looms as we close out the month of February and head into March. Note how the GEFS and EPS continues to tank the Arctic Oscillation (AO).  Winter’s not over, not by a long shot…

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″
