Roth/Pereira Day 3 Valid 12Z Tue Feb 18 2025 - 12Z Wed Feb 19 2025 ....THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL ALONG PORTIONS OF THE CENTRAL GULF COAST... Strengthening southwesterly winds ahead an amplifying upper level shortwave and an associated cold front are expected to draw deeper moisture into parts of the Gulf Coast, with PWs climbing to around 1.5 inches. This moisture along with increasing lift and instability may be sufficient for heavy rainfall rates. Models offer a modest signal for training storms ahead of a surface low that is forecast to develop and advance east along the coast Wednesday morning. This may help support localized heavy rainfall, with some potential for isolated flash flooding, especially in urbanized areas.
