\u201cAny convection that does manage\u00a0to develop will likely be high (temperature)-based and would pose a gusty wind\u00a0threat in any of the stronger cells,\u201d the weather service said in the bulletin.<\/p>\n
What\u2019s the forecast for Friday and beyond?<\/p>\n
\u201cLow to medium rain chances continue Thursday night into Friday\u00a0with a boundary (of a cold front) in the area,\u201d the weather service said. \u201cThere may be lesser coverage in any\u00a0showers or thunderstorms Friday due to the slight eastward\u00a0progression of the mid-level ridge during the day.\u201d<\/p>\n
