AREA FORECAST DISCUSSION National Weather Service Raleigh NC 250 PM EDT Mon Jul 13 2020

SYNOPSIS. A weak surface trough will linger over the region into tonight. Subtropical high pressure will then build across the region through late week.

NEAR TERM /TONIGHT/. As of 250 PM Monday .

Surface analysis shows a boundary oriented from northeast to southwest across North Carolina, primarily noticeable by a dewpoint gradient. Nearly all afternoon convection has formed along and to the south of this boundary across southern North Carolina, although there are some rogue showers and a storm north of US 64. Wind gusts remain the primary concern for severe weather with dry air aloft and modest values of DCAPE. CAPE is plentiful, although wind shear is minimal. In fact, with such little steering flow, storm motion has been slow, and with precipitable water values between 1.5 and 1.8, this raises the potential for flash flooding. The focus of storms should slowly shift to the I-95 corridor during the late afternoon, with only a slight chance of showers/storms remaining east of I-95 during the evening hours before conditions dry out. Expect typical North Carolina summertime lows overnight, with temperatures bottoming out in the lower 70s.

SHORT TERM /TUESDAY AND TUESDAY NIGHT/. As of 250 PM Monday .

As the boundary moves east along the North Carolina shoreline, the focus of precipitation will also move east. Have retained a slight chance of showers across southern and eastern counties, but really think that most precipitation should be contained to coastal areas. With a little bit less cloud cover around, high temperatures should creep up a couple degrees bringing all locations into the lower 90s. No showers/storms are expected after sunset Tuesday night, and lows will fall into the low to mid 70s.

LONG TERM /WEDNESDAY THROUGH MONDAY/. As of 121 PM Monday .

Mid level ridging will dominate the wx pattern over the Carolinas Wednesday and Thursday, resulting in above normal temps with heat index values 100 and below climo daily PoPs. The ridge will begin to weaken across the East Friday through Sunday as the ridge center shifts westward toward then over the Central Plains. By Monday, a weak trough will be in place over our region, between the ridge center over the Central Plains and the ridge center over Bermuda. Thus the chance for afternoon and evening showers and tstms will increase back to climo, or perhaps even a little above climo, Friday through Monday, along with temps a couple deg cooler thanks to increased cloud coverage and rain shower coverage.

AVIATION /18Z MONDAY THROUGH SATURDAY/. As of 105 PM Monday .

24 hour TAF period: Scattered to numerous thunderstorms are expected this afternoon, with the greatest activity across eastern ports such as FAY/RWI. While a thunderstorm cannot be ruled out at INT/GSO, had less confidence in those locations, and downgraded the precipitation mention to a VCSH mention instead of a VCTS mention. There should be no widespread restrictions from precipitation, although heavier showers/storms could produce brief restrictions that are not specifically mentioned in the TAFs. All precipitation should come to an end shortly after sunset. While some model guidance suggested that there could be restrictions around dawn, feel that any such restrictions would likely be related to where rainfall occurs today and that a mention of restrictions could wait until a later TAF package once rainfall has been observed.

Outlook: Generally VFR conditions are expected through Saturday. There is a chance of an afternoon or early evening thunderstorm, with details generally low confidence at any given location at this time.

RAH WATCHES/WARNINGS/ADVISORIES. None.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
