Current Temperatures Around The Local Area

An explanation of what is happening in the atmosphere over the coming days.

A calm few days of weather ahead of us.  It will be colder, but nothing extreme for this time of the year.  No block buster cold air in the forecast through next weekend (at least for our immediate local area).  A bit of a snoozer for weather folk.  Calm is good for all of you who have to travel.

It will at least feel more like winter than recent weeks.

Wednesday morning will bring some teens to the region (remember it is almost January)

A secondary cold front will bring a reinforcing shot of cold air on Monday night and Tuesday – I can’t completely rule out some snow flurries with the front.  Lot of dry air aloft – so the chances seem pretty low.  Perhaps our northwest counties.

New Years Eve and New Years Day should bring dry but chilly conditions.  I do not see any travel problems on either day.

The next precipitation maker arrives late this week.  See the extended forecast for the latest details on that event.  This system is anything but set in stone.

No major changes to the ongoing forecast.  I did mention snow flurries for Monday night as a second cold front moves into our area.

I have no major concerns through Thursday morning.

I have no severe weather concerns through Thursday morning!

Can we expect severe thunderstorms over the next 24 to 48 hours?  Remember that a severe thunderstorm is defined as a thunderstorm that produces 58 mph winds or higher, quarter size hail or larger, and/or a tornado.

Thunderstorm threat level is ZERO

No action required

 

rainfallforecast

How much rain should this system produce over our region?

A calm few days ahead of us.  No rain or snow.

 

winterstorm

Do I even have to tell?  No snow in the forecast through Thursday morning.  Sorry snow lovers.

I did mention flurries fro Monday night and early Tuesday morning.  This should not amount to much and many people might sleep through it (if flurries develop at all)

I am watching a system for Thursday night into Saturday night.  If the precipitation moves in fast enough then it could begin as a light wintry mix before changing over to all rain on Friday and Saturday.  As the system pulls away there might be a chance for the rain to turn back over to snow.

Some of the data holds off precipitation until later on Friday and brings the bulk of the precipitation into our region on Saturday.  Models are basically all over the place with this event.

This system is anything but set in stone.  The low could track further south or further north.  This would completely change the forecast.  Monitor updates.

The Canadian model has been great lately – some of the other models have been horrible.  The Canadian model takes this system pretty far south.  It does have some support from the other models.  If so then we might end up on the northern end of the storm.

We will just have to watch trends this week.

Here is the rainfall totals from the next storm.  Once again this is a big rain maker for areas to our south (same as the last storm was)

I did anticipate an active southern jet stream this winter.  So far it has not disappointed.

As mentioned above, I am watching a system for Thursday night (late) and Friday/Saturday.  An area of low pressure will move out of the Southern Plains into the Mississippi River Valley.  This area of low pressure will pull moisture northward into our area.

By Friday afternoon the cold air, that will be in place most of this week, will be shunted north and east.  Warmer air will move into our area by Friday afternoon into Saturday.

We might see the precipitation move in quick enough early Friday morning for it to begin as a wintry mix.  Warm air, however, is forecast to win out and if there is a wintry mix it won’t last long.

Widespread rain is likely on Friday into Saturday.  Still a bit early to know how much rain might fall.  If the low does pass close to our area then some areas could pick up an inch or so of precipitation.

The GFS model tracks this sucker pretty far south.  Could that mean more wintry precipitation at the end of the storm?  This will be one to watch.

gfs_ptype_slp_east2_26

All of the above forecast comments are 100% dependent on the storm behaving as expected.  Since this system is still several days away it would be best to check back for the latest update.  These winter systems can be tricky to forecast.

Colder air will move back into the region by Saturday night or Sunday.  This colder air may linger into next week.  Some of the data places a decent amount of cold air into our region next week (January 5th-9th).  Long way off and plenty of time to monitor.

Some of the long range data indicates a lot of cold air for the very end of January into February.  Perhaps sustained cold.

January may bring transient cold shots.

The long range cycle data is leaning towards another system around January 5th through 9th.  A lot of cold air behind that one?  Possibly.
