Trend Summary
The next 15 days begin dry and mild, with clear skies and daytime temperatures near 14°C through the weekend. Overnight lows dip near or just below freezing early in the week, especially on the morning of January 4th, when frost is likely. A shift occurs around New Year’s Eve as cloud cover increases and temperatures drop slightly. From January 1st to 3rd, light drizzle is possible with near-freezing overnight temperatures—brief frost on untreated surfaces cannot be ruled out, though no snow is expected. The most unsettled period is January 5th–7th, with prolonged light rain and gusty winds, peaking on the 6th. Rainfall totals are moderate but spread over many hours, so flooding is unlikely. The period ends on January 8th with drying conditions and clearing skies.
Temperatures trend cooler after December 28th, then rise slightly during the rainy stretch in early January. No significant warming or cooling extremes are indicated. Model runs in the past hour show stable temperature and precipitation trends, with low spread—confidence is moderate through the first week, decreasing slightly for details beyond January 5th due to uncertainty in timing and intensity of drizzle periods.
Practical Notes:
- Freezing overnight temperatures on January 2nd and 4th may lead to frost on roads and walkways. Exercise caution in the early morning.
- The wet and windy stretch from January 5th–7th may make outdoor plans uncomfortable—prepare for damp conditions.
- No snow is indicated at any time. Any precipitation falling near 0°C is expected to be rain or drizzle, with brief frost possible only on elevated surfaces during cold nights.
- Most days through December 30th are favorable for outdoor activity.
