| Area Forecast Discussion National Weather Service Lake Charles LA 402am CDT Sunday May 31 2020 Short Term [Today and Monday] This morning's surface analysis shows a 1020 hPa surface anticyclone centered over the Great Lakes and Upper Mississippi River Valley. A weak cold front extending along the southern periphery of this anticyclone is located over CWA where isolated to scattered showers are noted in the regional radar mosaic. The surface boundary is expected to remain along the immediate coast today and Monday as the high pressure shifts southeastward. As a result, showers and thunderstorms will continue to be possible, mainly near the coastal areas, today and Monday. However, most locations are expected to remain dry with temperatures climbing into upper 80s and low 90s. Long Term [Tuesday through Saturday] By Tuesday, return flow will redevelop over the CWA as the surface high progresses southeastward into the western Atlantic. This return flow will advect greater tropical moisture into the region which in combination with a slight weakness in the upper level height field will result in diurnally driven convection each day. Coverage of this convection is expected to gradually increase into the later half of the week with the increasing deep layer moisture. By next weekend, the forecast becomes more uncertain due to the potential for tropical activity across the western Gulf of Mexico. Ensemble guidance for late next week into the weekend is indicating the potential for a more robust surface circulation to emerge from the Central American Gyre (CAG) and to develop into a tropical cyclone. Since any tropical cyclone development would be linked to mesoscale features embedded within the CAG, there is not point in focusing on individual tracks or strengths of cyclones that are produced by ensemble or deterministic guidance 5 to 7 days out. Rather, the present time should be focused on reviewing one's tropical plan, checking one's preparedness kit, and monitoring forecasts from the NHC and NWS over the upcoming week. For now, the forecast for next weekend is based on a blend of WPC/NBM guidance with greater rainfall chances due to increased deep layer moisture in place over the region. Marine High pressure to the north of the area will result in light offshore flow through Monday. Weak convergence near the coast could trigger isolated showers and perhaps a thunderstorm, but most of the coastal waters remain dry. High pressure to our north will slide east on Tuesday, resulting in winds shifting from an offshore component to onshore. Increasing moisture will result in chances for showers and thunderstorms steadily increasing through the week. Additionally, there are indications of the potential for tropical activity in the western Gulf next weekend. Mariners should monitor forecasts from the NHC and NWS for late in the week through next weekend. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...None. |
