Forecast Wednesday Thursday

3 - Considerable 3 - Considerable
treeline 2 - Moderate 2 - Moderate
below treeline 2 - Moderate 1 - Low
Confidence: High - Timing or intensity of solar radiation is uncertain on Tuesday
High The forecast is based on high-quality information and the nature of the issue makes it possible to render a solid judgement. A 'high confidence' rating does not imply fact or complete certainty however, and such judgements still carry the risk of being wrong.
Moderate The information used to produce the forecast is credibly sourced and plausible, but it is not of adequate quality or sufficiently corroborated to warrant a higher level of confidence.
Low The credibility or plausibility of the information used to produce the forecast is questionable, or the information is too fragmented or poorly corroborated to make solid judgements, or there are significant concerns regarding problems with the sources.
