As of 144 AM Tuesday... KEY MESSAGE 1... Dry fuels combined with lower humidity and near record heat will promote fire weather concerns through the end of the week. No changes to the week as far as highs in the upper 80s to lower 90s and no rainfall through Saturday. The NC Forest Service has requested additional messaging along with their current state-wide burn ban. We issued an Increased Fire Danger Statement (IFD) the western Piedmont/Sandhills through 800 PM today. More statements will be needed Wednesday and beyond. KEY MESSAGE 2... A highly anomalous mid-level ridge will persist over the southeastern United States through late week, supporting an early-season heat wave with temperatures 15–20F or more above climatology. A highly anomalous mid-level ridge will persist over the southeastern United States through late week, supporting record or near-record heat across central North Carolina. Both the GFS and ECMWF deterministic and ensemble guidance remain in strong agreement depicting a robust 500-mb ridge centered over the Southeast and Mid- Atlantic. During this period, H8 temps are progged in the 15-17C range along with deep-layer thickness values approaching summer-like magnitudes. As a result, high temps will reach the upper 80s to lower 90s basically Wednesday through Friday, with the typically warmer locations southeast of RDU possibly seeing mid 90s. These values are 20F degrees or more above mid-April normals. Hazards associated with this heat may include early-season heat stress (especially vulnerable populations) due to limited acclimatization. See the climate section below for more details about the records that may be threatened with this heat wave. Key message 3...Late-weekend pattern transition possible with low- end rain chances on Sunday with fropa...followed by cooler temps. The ridge will gradually weaken and shift east over the weekend as a trough advances from the Plains. A cold frontal passage is expected on Sunday which may result in low-end rain chances. Behind the front, temps will trend closer to seasonal normals (low-mid 70s) early next week. && .AVIATION /18Z TUESDAY THROUGH SUNDAY... As of 104 PM Tuesday... VFR conditions will persist through the 24 hr TAF period. Sswly sfc flow will remain light this afternoon, with a few gusts of up to 20 kts possible at KFAY/KRWI this afternoon. Similar light sswly sfc flow is expected Wednesday. Outlook: Sub-tropical high pressure will favor warm, dry, and VFR conditions in cntl NC through Sat. A cold front will bring a low-end chance of showers to central NC on Sunday. && .CLIMATE...
