BIG IMPROVEMENT SUNDAY… December 19, 2009

We have some nice changes on the way for the end of the weekend.  Most of the cloud cover will be moving out tonight and therefore we should see a good amount of sunshine for Sunday afternoon.  Factor in a south wind and we could be experiencing a 15° temperature swing when you compare Saturday’s [...]

Thunderstorms for Wednesday? December 18, 2009

I want to say that we’re in for a wild weather ride next week.  Merry Christmas everybody!  Substantial warm air advection will take place late this weekend into early next week ahead of a deepening trough.

I have highlighted that trough which is somewhat negatively titled late Tuesday into Wednesday per the GFS.  When you see [...]

Model Confusion…Snow or Severe Weather? December 18, 2009

As frustrating as it can be, I love a challenging forecast. This is one of the reasons I love forecasting winter storms. Trying to peg down the details of a large and complex winter storm is rarely easy and the storm that is expected to develop next Wednesday and Thursday is no different. For the [...]

Friday’s Clipper System December 17, 2009

We had a beautiful afternoon across the area.  Southerly winds and a partly cloudy sky helped to kick temperatures into the low to middle 50’s.  Unfortunately the mild conditions will come to an end on Friday as a clipper system drops our temperatures.

A clipper system is similar to a regular cold front. Clipper systems are generally [...]

Travel Weather Through Christmas December 17, 2009

The dry and cooler weather will last through Monday. On late Tuesday and Wednesday a developing storm system could delay travel [...]

Friday’s Front…Cold Weekend December 16, 2009

Yesterday I posted about the possibility for snow on Friday.  The computer models have really moved that snow potential for late Friday night into Saturday morning across central Missouri where the best dynamics will set-up.

There’s still a chance of some flurries being squeezed out Friday night as the cold air moves in from the northwest; however, [...]

Dreaming Of A White Christmas… December 16, 2009

Well here we go, for all of those dreaming of a white Christmas we are nearing the home stretch. Christmas is now just 9 days away and there is a chance for some white on the ground Christmas morning. An official white Christmas is at least 1″ of snow on the ground at 7am Christmas [...]

Snow for Friday? December 15, 2009

The weather outside today was sunny and cold; however, another blast of cold air arrives for Friday, which could lead to some winter weather.  The long wave pattern looks to become rather active which leads us to think that winter weather will be possible over the next 10 days.

I want to first say the NAM model [...]

A Wet Year Is Ending Dry December 15, 2009

December [...]
