NOAA's Hurricane Outlook, Plus Rockies Disturbance Brings Heavy Rain Threat...

The "official" NOAA Hurricane forecast was issued today and, as expected, there are no surprises.  We have heard since April that the 2022 season would be another active one making this 8 straight years above average/normal.   Here's their forecast that offers a greater spread/range in the number of storms & hurricanes than most other forecasts.  I grabbed these graphics off of Zack Fradella's noon program.





Some of you may say their ranges are too broad giving them a better chance of being "right".  I agree.  An interesting fact is the past 7 years have seen preseason named storms and it ended up being active seasons above normal.   The last time we didn't have a preseason storm was 2014.  Look at the total number of storms that year!  I'm leaning toward a less active season IF we don't start off with an early storm.  12-14 named storms sounds about right to me.



Of course 2013 didn't have an early storm either, but look at the final total.  We still have an opportunity to get a named storm in May.  Look at the satellite views.




These swirls are at pretty high latitudes with colder water temps.  But if either drifts southward and starts firing off T-Storms around their centers, we've seen how quickly NHC reacts.   Our weather the rest of this week will not be from the Tropics.  Rather, a strong upper low moving out of the Rockies will sag pretty far to the south and should trigger heavy rains along the Gulf Coast tomorrow and Thursday.  SPC has a level 3 severe threat today and diminishes that tomorrow.  However, my gut tells me that could be revised upward.





Why?  Look at how the computer model (GFS) handles this system.






The 4 model graphics are valid for today, Wed. Thurs, & Friday.  The main energy won't pass to our east until Thursday PM with much drier and slightly cooler air coming behind the front.




The reason we'll have a heavy rain threat is we have a potent upper disturbance diving into a very juicy air mass with 70+ dew points.  Make sure you have the FOX 8 weather app to alert you in case warnings start coming out overnight into Thursday AM.
