Suchan Says: Pattern Shift Ahead

We have ourselves a great looking Saturday ahead with full sunshine and nice mild afternoon temperatures in the lower 60s.  Sunday is actually a pretty decent day although there will be times of patchy clouds and a 20% chance of sprinkles or a passing shower.  Highs on Sunday will be warmer reaching into the upper 60s.

Next week will see a significant pattern shift unfold as a deep upper level trough develops in the southwestern part of the country and “slowly” pivots east into Texas.  It will then most likely slowly move north as it opens and weakens.  This will keep some measure of rain chances in the forecast clear into next Saturday which is “Snake Saturday”.

Here are 4 charts or panels showing this upper level trough coming at us.  Moisture surges into the area ahead of this feature and it will increase dynamics to generate showers or a few thunderstorms Tuesday, Wednesday and Friday into Saturday most likely.
