Baltimore is set to experience a slight temperature dip today as a cold front exits, only to ramp back up into a sweltering weekend, as reported by the National Weather Service. The National Weather Service details that the passing cold front will bring temperatures down to the 80s to low 90s today, with dewpoints lingering in the lower to middle 60s. Meanwhile, a high-pressure system will slide in from the northwest and linger until Friday night.

For those in the central Shenandoah Valley and Virginia Piedmont, there might be a dry spell in the afternoon with isolated showers or thunderstorms potentially developing. However, these predictions have trended drier due to the high-pressure building. Heading into Friday and Saturday, moisture levels and temperatures are forecasted to rise, with the prospect of heat-induced thunderstorms, as per the National Weather Service.

This weekend, Baltimore heats up as humidity levels increase, pushing apparent temperatures into the 100s on Saturday. On this cusp of the weekend, a warm front brings morning showers and thunderstorms, followed by an afternoon threat with the potential for severe weather, including damaging winds, especially on Sunday. "The local area appears to be on the southern flank of the stronger belt of mid-level westerlies, generally running around 35 to 45 knots." according to the National Weather Service.

Sunday rounds off the weekend with a proactive weather front that could push heat indices to a sweltering 100 to 105 degrees. Showers and thunderstorms may continue to impact the area as Independence Day approaches. A stark change is expected with a high-pressure system forecasted to dominate early next week, which may bring some reprieve in the form of more moderate temperatures and northerly winds cooling the area down substantially.

For aviators, the pre-weekend changes won't go unnoticed, as possible isolated shower activity on Friday could lead to sub-VFR conditions by Saturday. "Sub-VFR conditions are likely Saturday with any showers and thunderstorms that move across the terminals." advised the National Weather Service. The agency anticipates a return to prevailing VFR conditions by Sunday night that should extend into Monday.

Baltimore's mariners should also brace for potentially rough conditions over the weekend. The marine forecast cautions that the approaching storms could necessitate Special Marine Warnings, and northerly winds post-front may reach Small Craft Advisory levels by Sunday night into Monday morning.

Lastly, coastal and tidal impacts are anticipated to be minimal today, but the situation could change over the weekend as water levels rise with the warm front. The area may see water levels reaching Action or perhaps Minor flood stages, particularly at more sensitive coastal sites.
