.Short Term [Tonight Through Monday]... The next cold front will affect the area during the day on Sunday through Sunday night with an increased chance of showers. All of the available guidance keep the main surface low well north of the area in the Ohio Valley with minimal instability expected. Thus, severe weather is not currently expected with this system, although an isolated rumble of thunder is within the realm of possibilities, mainly close to the coast. .Long Term [Monday Night Through Saturday]... A cooler airmass will move in behind the front for Monday night with a light freeze possible across portions of the area. However, with the upper flow quickly becoming zonal, a significant cool down is not anticipated. The next system will bring rain to the area by Wednesday into Thursday as an upper low over the southwestern states ejects into the Western Gulf. There remains some timing differences with the guidance, so PoPs are spread out fairly evenly between the two days. Once the timing becomes more clear, PoPs will probably rise one of the days and fall for the other. At the moment, most of the guidance keeps the associated surface low just offshore, which will limit any severe threat. Another shot of cooler air will follow this system for the end of the week. .Marine... Winds and seas will increase over the next day with advisory conditions expected to return on Sunday ahead of a cold front. Advisory conditions are also possible behind the front for Monday with improving conditions on Tuesday. By mid to late week, another system will bring increasing winds and seas once again. .Fire Weather... RH values this afternoon will drop well below 40%, but are still expected to remain just above locally critical levels. RH values will increase beginning Sunday ahead of an approaching frontal system. Dispersion values may be rather high on Sunday, primarily due to strong transport winds. .Hydrology... The next system arriving for the Sunday-Sunday night time frame appears capable of producing around a half inch to inch of rain across portions of the area with a few localized heavier amounts. These amounts will likely provide for a small rise in river levels, but they are unlikely to result in a return to flood stages at any of the forecast points. The system for the Wednesday-Thursday time frame may be a bit more significant with 1-2" of rain possible with localized higher amounts. When combined with the rains from the first system and already above average stream flows, a few rivers may approach minor flood stage late in the week. At this time, the progressive nature of the pattern is expected to keep rainfall amounts from getting high enough to produce more significant flooding.
