The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Caribou, ME wrote its last area forecast discussion before the first event at Aug 11, 11:32 AM EST, 2 hours 28 minutes earlier.
Area Forecast Discussion National Weather Service Caribou ME 1232 PM EDT Thu Aug 11 2022 .SYNOPSIS... A cold front will approach from Quebec, Canada today and cross the area late this afternoon into tonight. High pressure will build in from the west Friday through Saturday. Weak low pressure will lift east of the area Sunday followed by weak high pressure on Monday. && .NEAR TERM /THROUGH TONIGHT/... 12:30 PM Update... Clouds are filling in as expected with daytime convection across areas that had previously cleared. The cold front is located along or slightly east-southeast of the Saint Lawrence River in Quebec as of 16z and is drifting slowly southeast. Expect coverage of showers to increase over the next few hours across the North Woods and Saint John Valley with isolated to locally scattered thunderstorms also possible as around 1000 j/kg of SBCAPE is forecast to develop north of the Katahdin Region. Meager mid-level lapse rates, particularly above 500mb should limit the strength of storms that do develop. However, a couple of the strongest storms may be capable of gusty winds and perhaps some small hail. Expected coverage of such storms is not expected to be widespread enough to warrant inclusion in the forecast. Previous discussion: Water vapor satellite pictures show an upper trough moving east of Hudson Bay. This trough is expected to move into eastern Quebec and western Newfoundland by 12z Friday morning. A surface cold front moving into the Saint Lawrence River Valley will move into western Maine this afternoon, and should be along the Downeast coast by 12Z Friday morning. Showers and scattered thunderstorms will develop across the north woods by midday before moving east. The highest PoPs will extend from the central highlands north. The last of any thunderstorms that develop should end rapidly this evening, and showers are expected to end in the evening across the north with the area of showers to become more isolated to scattered across the Downeast Region. Bufkit model sounding across the north show anywhere from a few hundred to as much as a thousand J/KG of cape depending on the model. 0-6 km Bulk shear values are in the 30-40 kt range, and PWATs are on the order of 1.25-1.5". Clouds and some showers ahead of the main cold front along with a strong jet aloft that would tend to shear apart any storms that would try to get going above around 25K ft agl should dampen the severe threat. We are also reaching that point in the summer where climatologically things need to come together a bit better for a greater severe threat across the north. More sunshine and much warmer temps would lead to a higher threat of severe weather as the instabilty would be higher. Expect isolated to scattered storms with locally heavy downpours and an isolated threat of a few strong wind gusts. Given the isolated nature of any stronger wind/heavy rain will hold off on enhanced wording as it would have to be a very broad brush across much of the northwest third of the FA. Highs today will mostly be in the 70s with a few spots interior Downeast near 80F. Lows tonight will range from the mid/upper 40s in the NW Valleys, low to mid 50s elsewhere across the north, and mid 50s to low 60s south. && .SHORT TERM /FRIDAY THROUGH SATURDAY/... A large area of high pressure will begin to approach from the Great Lakes on Friday. Northwest winds ahead of the high combined with an upper trough over our region will bring a cool day on Friday with highs only near 70 over the far north and in the mid to upper 70s Downeast. The sky will turn out partly to mostly sunny. High pressure will continue to build in Friday night bringing a moonlit and cool night with lows down to the upper 40s in some of the cooler valleys to the northwest. This will be followed by a mostly sunny and seasonable day on Saturday as weak surface high pressure builds over and an upper trough dissipates over the area. Surface high pressure will remain across the region Saturday night as the weakening upper trough slides east. The upper trough will still be overhead and may produce a weak low off to our east. Latest guidance is showing this low off to our east to be too far east to bring rain. However, the upper trough may still be producing a few clouds in the area Saturday night. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... The weak upper trough over the area will continue sliding east and away on Sunday as surface low pressure continues well to the east. Some clouds and spotty showers may be over northeastern areas from the upper trough and the surface low well to the east. Otherwise, Sunday will be partly sunny with temps just a couple degrees below normal. High pressure will move off to the east Sunday night into Monday as a trough of low pressure digs into the eastern Great Lakes and northern Appalachians. The trough may begin to develop low pressure over the central Appalachians early next week. As high pressure moves off to the east and this low begins to approach clouds may begin to increase late Monday. The upper low crossing the area combined with weak low pressure to the south will bring a chance for some rain Tuesday into Tuesday night. Temperatures will be near, to perhaps a little below normal through early next week as this trough moves in. The chance of rain will persist into Wednesday as the surface low lifts toward our area and the upper trough remains just to our east. The trough and associated low should begin to lift out on Thursday. However, lingering low level moisture will keep the sky mostly cloudy. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... NEAR TERM: VFR this afternoon and evening with tempo MVFR in showers and possible thunderstorms from KHUL north. Predominately VFR tonight at the northern terminals. Conditions will likely lower to MVFR with possible IFR at the Downeast terminals in low clouds and areas of fog tonight. S to SW wind 5 to 10 knots today, shifting into the NW around 5 knots tonight. Locally erratic wind gusts possible in or near any afternoon thunderstorms from KHUL north. SHORT TERM: Friday...VFR. Light N wind Friday night...VFR. Light N wind. Saturday...VFR. Light NW wind. Saturday night...VFR. Light and variable wind. Sunday...VFR. Light and variable wind becoming SW near the coast. Sunday night...VFR, possibly lowering to MVFR Downeast. Light SE wind. Monday...MVFR lowering to IFR. E wind. && .MARINE... NEAR TERM: The wind and seas will remain well below small craft advisory levels through tonight. Patchy fog at times this morning and again this evening with more widespread fog possible late tonight. SHORT TERM: wind and seas will remain below SCA through the weekend and into early next week. Visibility should generally be good through the weekend but may lower early next week as moisture begins to lift north into the area. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
