Weather Pattern Outlook for Wed, Apr 9th through Thu, Apr 24th

Good Saturday Afternoon,

Check out the latest pattern outlook below. 

Note: For today, I’m using 00z Model run today for this update.  Also, it will be based on Zulu time.

Background Information

  • Got some exciting news.  New plots have been added from Tropical Tidbits.com.  Levi Cohen has been super in maintaining his great website. So, there are new plots from the European Ensembles, especially for the 6 to 10 day and 11 to 15 Day.  So, there are more neat analyses to check out and you can check out what type of weather pattern will be forming over the US the next two weeks.
  • I’m very excited to bring you something new to the website here. For folks that really get into tracking the weather, I’ve setup a nice high level set of tables that will show ensembles of 5 day ranges.  Right now, I have some model trends generally with GFS, ECMWF for 1 to 5 days for upper air height anomalies and temperature anomalies.  For the 6 to 10, I”m using 3 model cycles for the GFS ensembles.  Only the current ECMWF ensembles is available to the public. Then the same approach for the GFS and Canadian Ensembles. In addition, I’ve added in the Climate Prediction Center’s analog forecasts for the 6 to 10 and 8 to 14 days. The idea here is to see what general pattern is setting up across the US for each period.  Another great site I will add is CIPS. Its another great tool that is used in weather forecasting. CIPS is a historical analog guidance that the National Weather Service uses across the country. So, hopefully, you can use nice dashboard/table format and get an idea of how the future weather pattern is shaping up.
