845 FXUS64 KMRX 050519 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 119 AM EDT Fri Jun 5 2026 ...New AVIATION... .KEY MESSAGES... Updated at 117 AM EDT Fri Jun 5 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. && .AVIATION...
