Slow moving low pressure will impact the area early to mid next week. Near term until 6 am Saturday morning As of 930 pm fri... No changes planned with clear skies and cold temps as high pres builds in from the nw. Prev disc... Secondary high center develops over eastern nc tonight as an extension of the parent high over the great lakes region and will remain over the region through Saturday. This system will continue to produce cool dry conditions over the area. There is some concern tonight that patchy light frost will develop inland as winds decouple later this evening leading to strong radiational cooling with clear skies expected. With dewpoints forecast to be in the mid to upper 30s, will forecast lows in a similar range and forecast patchy light frost in areas where the low temps is forecast to be <= 36f. Winds may stay mixed from the southern outer banks to downeast carteret county where lows will be in the lower 40s, otherwise expect mid to upper 30s. Short term 6 am Saturday morning through 6 pm Saturday As of 330 pm fri... High pressure will remain over the area Saturday with continued clear skies, light winds and below normal temps.

Highs will moderate into the mid to upper 60s Sunday after a chilly start with lows Sat night in the lower 40s. Monday through Friday... Unsettled conditions are expected through the period as a energetic mean upper trough develops over the eastern us. Mon it appears that the surface high will delay precipitation onset associated with a upper low lifting ne out of the deep south and not expecting much rainfall before 8 pm (00z) with best chance south and west late. The upper low will become an open wave as it becomes absorbed phases with a northern stream shortwave Mon night and tue. This is when the models track a developing low across the area. There is a potential for heavy rains in excess of 1 inch Mon night into tue as high theta-e air gets advected off the gulf-stream . Will have to watch for isolated severe potential with inland tracking surface low Tue and backed low level SE flow but instability remains in question. Dry slotting will end the widespread precipitation threat Tue evening as the sfc low lifts NE of the area but additional mid level shortwave energy will drop from the northern plains towards the southeast Wednesday with a weak cold front associated with it and expected to push through thurs with a secondary cold frontal passage possible on Friday |
keeping the threat of showers in the forecast into at least thu. The warming trend will continue through Thursday with highs in the upper 60s low 70s inland Tue and low to mid 70s Wed and thu.

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. |
