UPDATE

No updates this evening as the forecast is on track.

SHORT TERM
(This evening through Sunday)
Issued at 318 PM EDT Sat Jun 22 2024

The familiar high pressure ridge aloft will be moving westward during this period, allowing a frontal passage ushered in by a shortwave crossing the Great Lakes. This front will be accompanied by convection. Rain chances don't really pick up until the latter half of Sunday afternoon, with the best precip chances actually during the evening. This means we will experience one more hot summer day Sunday before the front arrives with its Sunday evening storms and slight cool down Monday. More on that below.

LONG TERM
(Sunday night through next Saturday)
Issued at 318 PM EDT Sat Jun 22 2024

LONG TERM
(Sunday Night through Saturday)

Key Messages:

1. Frontal boundaries drive scattered to numerous showers and thunderstorms on Sunday night and Wednesday/Thursday.

2. Above normal temperatures continue into the upcoming week.

Our period beings with a strong upper level ridge off the Atlantic coast being forced out by a short wave and a corresponding frontal boundary. The front will move into our area from Sunday evening into Monday morning. We can expect some scattered to numerous showers and thunderstorms with the frontal passage. SPC has the NW section of our CWA in the Day 2 Marginal Risk, with the main risks being damaging winds and small to marginally severe hail. With the NAM suggesting DCAPE values of around 1000 J/kg, MLCAPE values of 1500-2000 J/kg, and SRH values of around 150 m^2/s^2, storm organization could be possible in the NW counties of the region, and this potential will continue to be mentioned in the HWO.
Precipitation amounts look to be a tenth to 1/4 inch, with potential for higher amounts in isolated thunderstorms.

This will see our CWA return to general northwest flow, driving some drier air into the area. However, dewpoints continue to trend high in the NBM runs, so the forecast will bump down the dewpoint values and high temperatures behind the frontal passage. Northwesterly flow will keep the air dryer, however this does not bring an end to the ongoing excessive heat for the period. This pattern continues until Wednesday when a 800mb jet begins to transport moist air from the Gulf of Mexico.

A cold front is expected to sweep across the area from the northwest on Thursday. While less likely to produce any severe weather, we can expect rain with accumulation up to 1/2 inch. After the passage of this front, the GFS indicates a return to a ridging pattern off the Atlantic Coast. The return to southerly flow will cause afternoon showers and storms to be the main cause for any precipitation for the rest of this period.
