STUBBORN LOW MOVING OUT

The same storm system that brough over 1″ of rain and a half inch of snow Tuesday through Thursday is still lingering for Friday.  The stubborn upper low will slowly inch east as the weekend gets underway.  A cool and unsettled weather pattern will take a break just in time for the weekend.  Some sun is possible Friday and better sky conditions will arrive Saturday and for Sunday.

MARCH ARRIVES – FASTEST WARMING MONTH OF THE YEAR

March 1st marks the unofficial open to Spring!  Meteorological Spring that is.  We take a serious turn to milder weather as the month progresses.  The month will warm 13° from the average high on the 1st of 45° to 58° on the 31st.

The days get even longer!  We gain the most daylight of any other month in March increasing by 1 hour and 18 minutes by months end.

METEOROLOGICAL WINTER ENDS TODAY

The final day of winter has arrived!  Well sort of – at least for record keeping purposes.  The months of December, January and February are the “winter” months or known as Meteorological Winter.  The actual astrological start isn’t until March 20th.

Winter 2012-2013 has been mild until recently.  Since December 1st 58 of the days have been above normal.  Most came in December when 25 of the 31 days were warm.  Snowfall came heavy late in the month as well with 14″ down by months end.  The snow has shut down over the past 8 weeks – only 4.8″ has fallen since January 1st or only one-third the normal.  (The normal is 14.9″).  Total snowfall for the season as of late Wednesday night is 19.8″.

Seasonal Temps

WINTER NOT LETTING UP

The pattern has turned cold and looks to remain rather cool for the next few weeks.  Cold weather indicators have gone negative and suggest that a blocking patter has/will develop over the North Atlantic.  This atmospheric set up portends colder air for the eastern U.S. and looks to remain intact through mid March.  Temperatures are expected to average below normal 8 to 15° off the normal high which is now 45° and increased to 49° by March 15th.

SNOW CHANCES RETURNING

The lack of snow and the nearness of it from the past 3 storms has the snow lovers pining for one more “decent” snow before the season ends.  There is hope if you are in this camp.  The series of storms that started 2 weeks ago this Monday will once again deliver another storm early next week.  This will be the 3 Monday/Tuesday storm over the past 16 days.  The new system is forecast to merge two low pressure systems over the central U.S. Monday night.  Storm track and location are key for measurable snow here.  Current projections off 5 various long-range models has the storm center from Dubuque, IA to as far south as Memphis, TN.  We will follow this through the weekend and of course have updates.
