Spring Like Weather Today

I can tell it's getting closer to spring.  Do you have allergies?  I have a whole host of allergies, including a ton of food allergies, but the tree pollen kicked into high gear yesterday and a lot of folks were starting to sniffle, including your friendly morning forecaster. I'm out of my maintenance medication and need to get on the ball quickly before it really starts to ramp up.  Hello Dr. Welch!  I'll be calling you soon! 

The weather continues to be mild and nice.  We managed to hit the 68 degree mark yesterday and should move back into the mid 70s today along with gusty south winds.  The fire danger issue is not going away.  We may have some relief Friday night into early Saturday with some shower and thunderstorm activity, but this will be just a drop in the bucket for what we need over the state.  Another storm system will be arriving by the Tuesday and Wednesday period of next week with a round of storms followed by colder air.  Until we see significant rainfall over a large area, the drought will continue to worsen and the fire danger issues will continue to get worse.  We may have temporary breaks where wind and humidity are not conducive to rapid fire weather growth, but the only big fix is a big rain. 

 The upper air pattern is trying to transition from a zonal flow to somewhat of an active flow aloft.  Next weeks system appears very strong in the model data suites, but the bulk of the energy may spread across the central and northern plains states.  Our surface winds Monday and Tuesday may be from 20 to near 40 mph from the south.  The air mass behind the Tuesday evening front will be cold with Wednesday possibly staying the 30s and 40s for the entire day! 

 

I thought it might be interesting to post some model output stats for the day so you can see what they look like.

 These outputs give forecasters a quick glance at the output of the computer model.  The different columns indicate the different weather data.  The only data I look at from these sets are the temperature and dew point numbers, and occasionally the cloud conditions.  I would rather use the raw data from Buf kit files or even interpolate temperatures from the model output in the grids than use the mos numbers.  But the key is to understand when one should use the numbers and when one should ignore them all together.  The joys of forecasting the weather.  I don't know if it's important to you if we say the high will be 73 and it hits 78, but it drives us nuts.   I think most folks are more aware of a blown forecast when the trends and expectations are not met.  For example:  When warm and sunny weather is forecasted and cloudy and mild air occurs.  Or when there's a high chance of storms, but only a few form, and most of them are not in your area.  Would you like to see a confidence system used for forecasts?  A confidence number of 10 would indicate absolute confidence and a confidence number of 1 would indicate no confidence.  If you have any comments, fire away:  alan.crone@newson6.net

 

Enjoy the weather.
