.DISCUSSION...
Issued at 217 PM EDT Thu Apr 9 2026

We start the period with quasi-zonal flow aloft and strong surface 
high pressure extending into our area from the east and northeast. 
High pressure will continue to extend over our area for the next 
several days and the flow aloft will eventually transition to upper 
ridging during the weekend.  Very low relative humidity values are 
occurring this afternoon and can be expected again tomorrow 
afternoon, and low afternoon relative humidity values will likely 
occur most days over the next week at least through Wednesday.  We 
will continue to see a warming trend into the weekend, and high 
temperatures will be well above normal by Sunday and continuing 
through the end of the period (next Thursday). Some record highs may 
be approached or possibly exceeded during the weekend into next 
week, with the days with records most under threat currently looking 
like Tuesday and Wednesday. Record high information for the weekend 
and beyond is included below for easy reference:

Precipitation chances are low at best for the period.  A weak and 
moisture starved cold front will sag briefly south into our northern 
areas Saturday, and a few northern spots may see a sprinkle or 
shower Saturday although chances for measurable precipitation look 
low. By Thursday a front approaching from the west may bring a 
better chance for convection into the area. However, the details 
that far out are still murky as model consistency has been poor, and 
model trends have generally been to slow the arrival of 
precipitation for our area.
