Here Comes The Rain…Again

By · April 23, 2013 at 1:12 pm

The shelf life on our dry weather is set to expire this afternoon.  Before the rain arrives highs will near 70° in Indianapolis, and should eclipse that mark in eastern Indiana where clouds are thinner.

Rain in western Indiana will push east into the Indianapolis metro by 3pm, and become likely area wide for the evening.

Rain amounts will range from .50″ to 1.5″, with the heaviest amounts possibly falling along the Wabash and White River basins.  This is not good news with portions of both rivers still at moderate to major flooding levels… and remain under Flood Warnings until further notice.

The forecast focus quickly shifts to a temperature tumble that occurs behind the passage of cold front overnight.  Temperatures Wednesday afternoon will be stuck in the 40s… a good 20° colder than today!

High pressure settling overhead provides the ingredients for patchy frost potential Thursday morning: clear sky, light wind and cool/dry air.

This will allow maximum raditional cooling, and aid in temperatures plummeting into the lower 30s.  I expect Frost Advisories and/or Freeze Watches/Warnings to be issued in future forecasts for damage potential to tender vegetation.

Thursday morning will be the coldest temperature in the 7 day forecast, with a decent warm up this weekend.  Long-range models continue to suggest a little weakness in the atmosphere over the Ohio Valley Saturday/Sunday… and it’s enough to warrant a chance of precipitation.  Stay tuned for updates.
