Wednesday Forecast: Rainy Midweek

Updated 11.05.13 @ 3:43p

Zionsville, IN Clouds are hanging tough this afternoon and rain isn’t too far off. Rain will increase Wednesday, becoming widespread the second half of the day. MUCH colder air will then blow into the region Wednesday night and Thursday.

Wednesday will feature another gloomy day with rain overspreading the region from west to east. Scattered showers will be present through the morning hours before giving way to steadier, heavier rainfall during the second half of the day. Latest data suggests the cold front is speeding up from the last forecast update and this should result in a FROPA (frontal passage) Wednesday night. It’ll also be a windy day, with southwest gusts of 25-30 MPH during the day, shifting to the northwest Wednesday night.  Colder air will pour into the state behind the front, setting up a chilly, blustery Wednesday night and Thursday.

Status-weather-clouds-iconThursday: Partly cloudy; 33/ 47

A blustery northwest wind will blow Thursday and combine with a partly cloudy sky and an unseasonable chill to create a rather cold day. Winds will gust upwards of 20 MPH from time to time.

 

Status-weather-clouds-iconFriday: Partly cloudy; 30/ 51

A hard freeze will greet us as we prepare to wrap up the work week. Widespread lows around 30 will be commonplace before partly cloudy skies help temperatures rise into the lower 50s Friday afternoon.

 

Status-weather-clouds-iconSaturday and Sunday: Partly cloudy; 40 Sat, 36 Sunday/ lower to middle 50s

High pressure will remain in control of our weather Saturday.  While a weak storm system will pass through the upper Great Lakes region, it’ll remain well north of our area. Southwest breezes could gust up to 20 MPH Saturday afternoon. Otherwise, we’re looking at some mid and high level cloudiness and middle 50s Saturday afternoon and lower 50s Sunday.

Status-weather-clouds-iconMonday: Partly cloudy; 38/ 50

Dry and slightly cooler than normal conditions will greet us as we kick off the new work week.

 

Status-weather-showers-day-iconTuesday: Scattered shower (0.10); 36/ 50

The early look at next week shows more questions than answers.  For now we forecast scattered showers as our next weather system approaches from the west, but we caution this is a low-confidence forecast.  Be sure to stay tuned as we update things moving forward.

Wet Pattern Continues

While the midday model data continues to flip flop on the temperature outcome next week, one thing seems rather likely and that’s the idea we remain in a pattern that will produce significant rainfall over the next 10 days.

Let’s take a look at the ECMWF, GFS, and GEM (Canadian) for precipitation amounts over the next 7-10 days.

Model data paints a wet picture of widespread 1.5″-2″+ type rainfall totals over the upcoming 7-10 day period.

Two Totally Different Solutions For Next Week!

I wanted to quickly post on two totally different scenarios for next week.  Two of the more powerful forecast models we use to look into the mid-long range are in separate worlds when it comes to the weather pattern the middle to latter part of next week.

Here’s a look at the GFS upper air pattern:

gfs_z500_sig_east_38

Note the eastern ridging which would lead to well above normal temperatures during the middle to latter part of next week (by as much as 10 degrees above average), along with dry conditions.

HOWEVER, here’s a look at the European’s forecast upper air pattern late next week:

ecm_z500_anom_east_11

This would certainly be quite the significant storm for the Northeast, but the implications here are vastly different from that which the GFS shows above.  Instead of warmth and dry conditions, we’d deal with highs in the middle 30s and overnight lows in the lower to middle 20s.  Additionally, we’d also “enjoy” (okay, some folks would “enjoy”) snow showers and snow squalls the middle to latter portion of next week, as noted per the European below, including a lake Michigan connection.

Needless to say, we have a lot to sort out in the coming days.  We’ll be here to do just that.  Make it a great Tuesday!
