Marine Weather and Tide Forecast for Canton, MS

DISCUSSION
Issued at 304 PM CDT Sat Jun 14 2025

Tonight and Sunday: Mid afternoon water vapor imagery/RAP analysis showed a shortwave trough over northeast Mississippi and another shortwave over central Louisiana. The northern shortwave will continue shifting east tonight while the second shortwave will continue moving northeast into the central portions of our CWA
Latest surface analysis had a ridge across the northern Gulf from the east. This surface ridge will help maintain low level moisture across our CWA through Sunday. Daytime heating of our moist airmass combined with the shortwave will lead to a scattered to numerous coverage of convection this afternoon through early evening.
Although the convection will see a distinct diurnal trend, there will remain a low chance of redevelopment through the night in the north. Although parameters aren't that favorable for severe storms, a few strong to severe storms can't be ruled out during peak heating this afternoon. Sunday another Shortwave will be dropping over our CWA from the northwest. This shortwave expected to combine with daytime heating of our moist airmass and lead to the development of numerous coverage of convection. This convection is progged to get an early start and hold afternoon highs a few degrees cooler than today. Thanks to our moist airmass, morning lows will be slightly warmer than normal. /22/

Sunday night through Friday night: Overall, we expect a warming trend with a gradual decrease in rain chances as we go through this upcoming week. The weakening trough over the lower/mid MS Valley will transition to a relative weakness between expanding subtropical high centers, one over the southwest CONUS and another over the western Atlantic, during the early week. Later in the week, the trough will dissipate entirely, and a strong subtropical ridge should become the primary weather influence, resulting in above normal heat and reduced rain chances. Somewhat of a wild card for late week in terms of storm potential will be shortwave trough passing through the westerlies well to our north in the Wed night to Thu timeframe that could support some storm organization, but this is low confidence. /EC/

Main concern this evening is with lingering SHRA and TS across southeast AR and north MS. Most of this activity should diminish during the early to mid evening with mostly dry conditions overnight. MVFR ceilings and patchy fog are possible tonight into early Sunday morning, but VFR conditions should return shortly after sunrise. Another round of SHRA and TS are expected Sunday, with greatest coverage in the afternoon to early evening. /DL/
