NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jun 16, 3:00 PM CST, 1 hour 57 minutes earlier.
Area Forecast Discussion National Weather Service New Orleans LA 400 PM CDT Sun Jun 16 2019 .SYNOPSIS... Latest surface analysis showed a 1017mb over Georgia, north Florida, and northeast Gulf. Southeast flow was present over the forecast area with dewpoint readings in the upper 60s to mid 70s. Precipitable water values on the planer view around 1.5 inches from central Mississippi to southwest Louisiana and 1.7 to 1.8 inches from east central Mississippi to Mississippi coast to Mississippi Delta. Upper air analysis at 500mb the Atlantic ridge over southeast U.S. and vigorous short wave over western Oklahoma and another northeast Texas. In addition, 500 mb temps were around -8 to -9C. Mid layer instability was present to support isolated to scattered convection over the region this afternoon. && .DISCUSSION... Surface high/ridge will remain in about the same general orientation through early in the week. The daily changes in the forecast will be mainly due to shortwave features in the mid to upper levels moving across the southern Plains into the lower Mississippi Valley. A short wave near the Texas/Louisiana border has provided enough focus for convection across the central Louisiana. Surface heating and mid layer instability is sufficient for a few storms to pulse up to strong to briefly near severe limits with the main threat being damaging winds. A few showers and thunderstorms may linger into the evening hours, mainly well inland from the coast, otherwise most of tonight should be dry in most locations with warm lows in the 70s. The main short wave over western Oklahoma will track east across the Mid South Monday and Monday night. An associated trough will track across the west Louisiana Monday morning and Southeast Louisiana and Mississippi Monday afternoon and Monday evening. The trough axis will pool moisture and precipitable water will increase to near 2 inches or slightly higher in the afternoon, so have maintained the higher/likely chances for showers and thunderstorms from inland south Mississippi into inland southeast Louisiana where a convective complex could move through the region. Some stronger storms with gusty winds and heavy downpours are likely. The stronger shortwave trough should move through early Tuesday. Residual moisture will linger and additional minor shortwaves may move through in west-northwest flow and interact with moisture. Ergo, will maintain a good chance of convection over the region Tuesday and Wednesday. Can not rule out gusty winds and heavy downpours will again be possible on Tuesday. Temperatures should be at least a degree or two cooler for the highs on Monday and Tuesday with the increase in convection. Progressive westerly flow aloft will maintain a track for low amplitude shortwave troughs to move west to east across the Central Gulf Coast Wednesday into Thursday with the southern extent of some convective complexes possible moving through at least the northern portion of the forecast area. Precipitable water values are not forecast as high as Monday and rain chances will be slightly lower Wednesday through the end of the week. Some stronger storms with gusty winds may occur due to the stronger westerly winds in the mid levels. A subtropical ridge should then expand out of the tropical Atlantic into the Gulf of Mexico and central to eastern Gulf coast Friday and Saturday, so a drier and warmer pattern is likely to return. 18 && .AVIATION... VFR conditions will prevail through most of the period for all terminals. Light south winds expected expect higher in and around any isolated storms this afternoon and evening. PROB30 for all terminals in the afternoon and evening hours as isolated summertime type convection is possible this afternoon and early evening. && .MARINE... Southerly flow will continue through the entire forecast period as surface high pressure sits of the Atlantic southeastern coast. Showers and thunderstorms expected to increase in coverage on Monday and Tuesday while synoptic winds will decrease. Southerly winds expected to increase late week as gradient tightens and surface high builds westward into the northeastern gulf. Chances of showers and storms will decrease by the end of the week. && .DECISION SUPPORT... DSS code: Blue. Deployed: None. Activation: None. Activities: Flood warnings continue along the Mississippi. Decision Support Services (DSS) Code Legend Green = No weather impacts that require action. Blue = Long-fused watch, warning, or advisory in effect or high visibility event; Marginal risk severe or excessive rain.
