Burst Of Snow This Afternoon; Storms And “Rumors” Of Storms This Upcoming Week…

The day is starting off on a cold note with some fog and low clouds around, but at least we’re dry (for now). That will begin to change here in a few hours as a burst of snow moves into the city around lunchtime. A brief period of moderate to heavy snow may whiten the ground just north of the city before a transition to a cold rain for the better part of the afternoon.

Further north, cold air will hang on longer and a more significant period of snow is expected through the afternoon and early evening. In fact, periods of heavy snow can be expected, including snowfall rates up to 1″ per hour at times. If you have travel plans to places such as Ft. Wayne, South Bend, or Logansport, we’d recommend preparing for slick travel and snow covered roads can be expected. This will be a wet and heavy snow. Pavement impacts will require salting and plowing across the northern 1/3 of the state this afternoon into the evening.

Here’s our snowfall forecast today:

The attention will then shift to a period of moderate to heavy rain through the evening and into the overnight across the I-70 corridor. By the time all is said and done Monday morning, widespread 1″ to 1.5″ is expected with the passage of this storm system. Good news? Most of the rain should be south of our area by the morning rush Monday.

High pressure will then settle into the Ohio Valley as we move into Monday evening and Tuesday, allowing a briefly quieter period of weather to arrive on the scene.

By this time, however, all eyes will shift to the southwest and our next storm system that should be brewing. While models differ on the specifics with this storm, the overall upper pattern suggests we need to remain on our toes with respect for the potential of additional winter weather stretching from the mid-MS Valley Wednesday, Ohio Valley Wednesday night into Thursday, and interior Northeast Thursday into Thursday night. A brief, but potent shot of arctic air would follow to close the work week- especially if we can get some snow down.

Should snow get laid down with this system across the OHV region, a cold arctic high would be capable of sending temperatures into the single digits to close the work week.

Stay tuned…

Long Range Update: Latest EPO/ MJO Implications…

Before we dig into the late-February pattern, there’s no let-up in sight with respect to our current active weather pattern. Just next week alone, we’re tracking (3) systems:

I. Sunday

II. Wednesday

III. Thursday-Friday

This is all part of the big battle taking place between a persistent southeast ridge and western trough. The tight thermal gradient between these features will help “fuel” continued active times, and above average precipitation next week. As mentioned this morning, at times we’ll have to deal with bouts of moderate-heavy rain, and at others, sleet, snow, and freezing rain.

An active weather pattern will continue as the ‘mean’ storm track cuts right through the Ohio Valley next week.

Looking ahead, we continue to build our longer range forecast by using “base ingredients” that feature a 50-50 split of the MJO (Madden Julian Oscillation) and EPO (East Pacific Oscillation).

The MJO maintains a warm look, rolling things into Phase 5-6 over the next few weeks.

As you know by now, these are warm phases- especially across the eastern portion of the country.

The “saving grace” for fans of at least being on the playing field for a chance of wintry weather in such warm MJO phases is the negative EPO. There’s great model agreement that this negative EPO will continue into the middle part of the month and this will keep us on our toes for wintry implications as storms track through the region. Conversely, there’s reason to buy into a “blow torch” regime to close the month, as the EPO flips positive and combines with the Phase 5-6 of the MJO.

To no surprise, given the above, we see the new European Weeklies showing a warming trend (after the fight over the upcoming week) for late-February.

The JMA Weeklies from this morning (for the Weeks 3-4 time frame) would agree.
