Warm May On The Way?

As our attention shifts to May, we wanted to share some of our thoughts on the upcoming month. Due to licensing issues, we’re not allowed to share all of the forecast models that we look at here with you, but did want to give you an idea of some of the data we’re looking at.

The month is likely to open up with an anomalous pattern in place, including one that will support a rather significant coastal storm along the SE coast.  That said, as we progress a bit deeper into the month, guidance suggests a much warmer pattern awaits for those locally across the Ohio Valley and Mid West.

Using a combination of model guidance, here’s an idea of what we’re projecting the upper air pattern to look like as we open the month and progress into the middle of the month.

May10th

As a whole, the majority of forecast data, including analogs of weak El Nino events of the past would imply a warmer than normal May is on the way.  Note the warmer anomalies across the mid South and Ohio Valley region.

The CFSv2 also is in agreement with the warm idea for May.  Areas where cooler air will be more likely?  The SW and northern tier regions.


Precipitation for April has been running above normal across our region and across the southeast, as a whole.  This is a good sign if you don’t like exceptionally hot and dry summers.  Precipitation this time of year can set the tone for both as we move into the summer months ahead.

  

For the month of May, we anticipate near normal precipitation (right around 5″), but stress that precipitation isn’t always uniform this time of year as thunderstorms can dump locally heavier totals.

Wet Today; Much Better Sunday!

  • Wet, at times, today
  • Increasing Sunday sunshine
  • Small rain chance mid week
  • Warming trend late week

SAT_EUS_WVENH_ANIThis morning’s water vapor loop, courtesy of Weathertap.com, shows low pressure and the associated “big spin” over the mid section.  This will continue to slowly track east, southeast as we go through today and will provide the chance of showers and embedded thunderstorms at any point today into the evening hours.  Severe weather is possible across southern IN on south into KY and TN.  Heads up if your travels take you that direction today and have a way to get the latest weather information.  A much brighter Sunday is ahead and this will set the stage for a calmer week overall when compared to this past week.

hires_ref_indy_11Forecast radar, courtesy of Weatherbell.com, shows heavier and more widespread rains lifting into the region early this afternoon.  Today’s rainfall totals, however, don’t look as heavy as what was expected earlier this week.  Now we’re thinking most will fall in the 0.50″ range, with locally heavier totals under spots that see a thunderstorm.

Frosty Weather Turns Wet Saturday…

Screen Shot 2015-04-22 at 7.02.51 PMHighlights:

  • Frosty start Thursday and Friday for some
  • Wet, chilly, and raw Saturday
  • Brighter 2nd half of the weekend
  • Watching next week

4Tonight’s water vapor loop, courtesy of WeatherTap.com, is showing drier air making it’s way into our region.  This will set the stage for plentiful sunshine Thursday and Friday (well deserved, I might add :-)).  Winds will also begin to diminish this evening.  The combination of winds going calm and clearing skies will promote the chance of a frost and freeze across central IN tonight (and likely again tomorrow night) as reinforcing chilly air pours into the region.  Those with ag. interests be sure to take note.

Attention then turns to the weekend and we’ll label it as “half-n-half” for now.  A wet, chilly, and raw Saturday should give way to increasing sunshine Sunday.  Early to mid next week will provide a new set of challenges and we’re leaning towards the wetter solutions yet again.  Keep in mind the drier forecast model sets (GFS in particular) had to come around and play catch up to those leading the way Saturday (EC and GEM).  Expect changes and stay tuned.

1Forecast lows tonight, thanks to Weatherbell.com, are suggested to fall into the lower to middle 30s.  Should the wind go calm then expect a few readings around 30 degrees.  We’ll likely dip near these readings again Friday morning.

2After a dry close to the work week, moisture increases late Friday night into Saturday morning.  Expect a wet Saturday with early rainfall numbers projected in the 0.50″ to 1″ range.

Rain Early Wednesday Morning; Chilly Pattern Continues…

Screen Shot 2015-04-21 at 9.39.23 PMHighlights:

  • Unseasonably chilly air arrives behind a band of showers
  • Needed dry time Thursday-Friday, but frost potential looms
  • Wet, cold, and raw Saturday

It’s been a chilly and WINDY open to the week.  After a day of sunshine Tuesday, clouds thickened Tuesday evening and showers aren’t far behind.  We forecast a band of light to moderate rain to move north to south during the overnight period- particularly between 1a and 5a.  Unseasonably cool air will be the rule as we wrap up the work week and head into the weekend.  A new storm system looks to deliver widespread rain Saturday.  Factor in temperatures running well below average and you have the makings for a rather nasty Saturday (a far cry from last Saturday’s sunshine and 80 degree warmth).

1A band of showers will move through central IN Wednesday morning and will be followed by another push of unseasonably cool air.  Forecast radar shown above, courtesy of Weatherbell.com, shows overnight rain moving through the region.  Between one tenth and one quarter inch is a good bet.

3High resolution forecast models suggest many dip to around freezing Thursday and Friday morning.  Those with ag. interests, take note.

2Wet weather returns Saturday.  The European and Canadian forecast models led the way with this system and now the GFS (shown above) is playing catch up towards a cold and wet Saturday.
