.KEY MESSAGES...
Updated at 133 PM EDT Thu Jun 4 2026

- The dry weather pattern will persist for the rest of the week. Low 
dew points and a touch below normal temperatures to start, then 
gradually warming temperatures and increasing humidity.

- Rain chances return as we head into next week, but certainty is
  lower due to model discrepancies.

.DISCUSSION...
Issued at 133 PM EDT Thu Jun 4 2026

Currently another sunny day with moderate temperatures and lower dew 
points and relative humidities. The upper level ridge bringing this 
weather will slowly move off to the southeast, while the surface 
high will slowly edge off of the Carolina coasts by this weekend. As 
a result of the blocking high, our area will be in a dry pattern 
with gradually increasing temperatures and dew points. 

Moving into next week, an upper level low across the southwest will 
try to merge with the northern flow across the US/Canada border 
region. Odds are good that precipitation chances return to the area 
as early as Sunday, but the weak flow paired with a possible west to 
east frontal boundary over us or to the north, makes any details at 
this time fairly uncertain. Return flow will bring increased 
atmospheric moisture, decreasing the stability next week.

With no major strong synoptic level forcing heading into next week 
expect the models to continue to have a hard time with regards to 
exact location of the places that will get precipitation.
