Low pressure is really wrapping up over the Great Lakes region this morning. Talk about fresh water fury… A byproduct of such strong low pressure is evident in the expansive…

We wanted to touch on a few items of business this evening. There’s a lot of weather going on this week…
Monday will feature drastic changes in the weather department across central Indiana:
Thanksgiving Cold And Snow:
Temperatures will be much colder than average (low to mid 30s for highs and middle 20s for lows). We’re still tracking a weak disturbance that could distribute light snow across central Indiana Thanksgiving Day. Accumulations, if any, would fall in the dusting to less than 1″ range.
Opening December Warm:
We’ve been talking about how this exceptionally cold and wintry early season pattern would have to “relax” at some point and that appears to be the case as we open December. The potential is there for well above normal warmth for the first week to ten days of December before we reload the pattern and introduce colder, more wintry times for mid and late month (anyone dreaming of a White Christmas)?

Wet And Windy Weekend…Some spots saw a touch of light freezing rain during the wee morning hours. That’s now long gone as temperatures have risen into the upper 30s as of this forecast package. Temperatures will continue to “warm” into the lower 50s today (today’s average high is 49) with scattered showers dotting the central Indiana landscape from time to time.
Much heavier and more widespread rainfall will lift north into the area Sunday afternoon and we forecast embedded thunderstorms along with strong and gusty winds for the second half of the weekend. Widespread 1 to 1.5″ rainfall is likely Sunday with locally heavier totals. As mentioned, the other big item of business will be the wind. Winds will likely gust towards 50 MPH in spots as strengthening surface low pressure lifts north Sunday night into Monday.
Colder Air Returns…The period of milder air will be very brief as temperatures return back to well below normal values Monday afternoon and continue through the big Thanksgiving week ahead. Some lingering wrap around moisture may lead to a few flurries or scattered snow showers Monday afternoon with falling temperatures and continued strong and gusty winds.
More Substantial Snow Maker For Thanksgiving? Details remain sketchy, but computer modeling continues to suggest we need to keep on our toes for the potential of light accumulating snow Thanksgiving. Snow or not, temperatures will be much colder than normal as the arctic hounds come calling yet again to set up a frigid Black Friday for shoppers.
Upcoming 7-day Precipitation Forecast:

It may only be November, but we’ve been locked in the grips of Old Man Winter for the past few weeks (really since the early season snow back at Halloween). While some “relaxation” will likely occur at a point during the first half of December, simply taking a look at the latest Sea Surface Temperature anomalies has to put a smile on the faces of those wanting cold and snowy weather for the upcoming winter.
Let’s take a look at the highlighted features above, starting in the Atlantic and moving towards the Pacific.
1.) Warm water off the eastern seaboard: Suggests some ridging is likely from time to time that could force would-be east coast storms inland. This is a factor in our forecasted above normal snowfall for the winter of 2014-2015.
2.) Modoki El Nino: A Modoki event, or central-based, El Nino is far different than an east-based El Nino event and the associated “blow torch” that can ensue for the winter months. Computer modeling continues to suggest a weak to borderline moderate Modoki event is in the cards. The sensible weather here in the states is vastly different from this type of event than many of the broad-brushed El Nino impact maps you may see on various media outlets. This is a cold, snowy look for many central and east.
3.) North-central PAC Waters: Water temperature profiles in the north-central PAC region continues to be an item we at IndyWx.com lean heavier on in looking at our longer range forecast outlooks. The ring of warmth around the colder north-central anomalies in the Pacific suggests plenty of Alaskan ridging ahead in the coming months. Downstream impacts? Central and eastern troughiness and associated colder than normal air.
As we state, there are MANY drivers that impact the weather, and this is simply taking the SST anomalies (1 ingredient) and dissecting the impact that they alone would have on the region. There are many other factors that we look at as we forecast long range weather. Taken verbatim, the SST anomalies suggest we’re on the right track suggesting a colder, snowier than normal winter looms… By the way, if you haven’t seen our winter outlook that was posted back on 10.19.14, you can view it here.

Good morning and happy Friday! We’re dealing with more unseasonably cold weather today which will result in needing the heavier coats and winter attire tonight as you head off to…
