Nearing 60° Sunday!

By · December 15, 2012 at 7:39 pm

Temperatures continue to creep up this evening…as balmy, saturated air pushes into Central Indiana.  This is resulting in areas of drizzle/light rain, and unseasonably mild lows in the 50s.

It’s certainly not a pretty picture from HD Skycam tonight.  Pockets of dampness will linger into Sunday morning, but I do expect some improvement by the afternoon… possibly even some peeks of sunshine.  The balmy start, persistent southwest wind, and even minimal solar radiation will allow highs to near 60°!

To put this into perspective.  The high will be closer to the record of 65° (1984), than the average of 38°!  ”If” Indianapolis hits 60°, it would be the 5th time this month.

Areas south of I-70 and east of I-65 have the best shot of of eclipsing the 60°.  Regardless it’s going to be well above normal in all backyards across the viewing area.

We’re keeping a close eye on Monday night/predawn Tuesday morning for the possibility of a period snow.

The latest FutureTrak 13 model data suggests rain will increase Monday afternoon along the I-70 corridor.  The moisture will team-up with a strengthening upper-level disturbance and cold air.  This may cause the rain to mix or changeover to all snow after sunset Monday.  Confidence is low on this scenario, but it’s a model trend we’re watching for progression.

Another storm shows up in the 7day forecast on Thursday.

(Click to enlarge)  On this model projected path it would be more of a rain/wind maker for Central Indiana…with the heavy snow band impacting the western Great Lakes.  But confidence is growing on this storm dragging in much colder air Friday and into next weekend.  To be determined if this will be a prolonged cold spell, or the beginning of an active storm pattern in the GL/OHV (Great Lakes/Ohio Valley).  Or both?!

Thanks for reading the blog and hope you enjoy the rest of your weekend.
