Following dry conditions early this week across the United Kingdom, showers will threaten to dampen Guy Fawkes Night bonfires and fireworks on Thursday.
"A warm front will be advancing throughout the day," AccuWeather Meteorologist Tyler Roys said.
Rain will spread across northern Ireland in the morning before impacting western Scotland, northern England and Wales in the afternoon hours.
Showers will spread across the U.K. for Thursday evening, but they will be spotty and fast-moving.
"It's going to be overcast for the U.K. as a whole," Roys said. "Any showers around could put a stop to fireworks, but the rain won't be steady."
A few locations in eastern England could escape with a dry night.
Despite breezy conditions, low temperatures will be milder than normal for most. Lows across England and Wales will range from 10-13 degrees Celsius (50-55 F), well above normal for this time of the year.
Northern Ireland will be between 9 and 12 C (48 and 53 F), and Scotland will near 10 C (50 F) by the coast and 7-9 C (45-48 F) well inland.
Those searching for traditional festivities will find burning crosses, fireworks and a massive bonfire in Lewes, Sussex, beginning at 5 p.m. on 5th November.
Festivities at Plymouth Hoe will also light up the night with a bonfire beginning at 7:30 p.m. and fireworks at 8 p.m.
Several more rounds of showers moving across Great Britain through the second half of the week will pose similar problems for weekend events.
"A series of fast-moving storm systems will continue the threat for rainfall on Friday and Saturday," AccuWeather Meteorologist Eric Leister said.
The rain won't be constant, but those headed outdoors may want to pack an umbrella.
Child-friendly activities will kick off at Coram's Fields in London at 5 p.m. on 6th November while more adult-themed activities will take place on 7th November at Alexandra Palace.
Saturday will also welcome guests to Sparks in the Park in Cardiff, the biggest annual fireworks event in the whole of Wales.
